Se ha actualizado y ya funciona !!!!

[Pablopadel]

Gente espero que esto les sirva a todos. El mio volvió a funcionar. lo primero que hay que hacer, porque todos lo resetamso de origen, es agarrar un dispositivo desde donde transmitir, cambiar la fecha a 6 de marzo y desde el home volver a conectarlo. luego apagas la TV y a la hora mas o menos la enciendes y va a aparecer un cartel que dice bajando actualizacion, luego se reinicia e instala. Y en mi caso ya pude volver a transmitir desde todas las aplicaciones

[Pete90]

Ragazzi sono tornato operativo mi è venuto il dubbio Ho spento e riacceso il Chromecast al riavvio aveva l'aggiornamento si è installato e ha ripreso a connettersi col telefono tramite Google Home Grazie mille Speriamo di non avere mai più di questi problemi e buon lavoro a tutti e buona visione a tutti Io sono Torino Italia

[Germanpv]

Ya funciona , se actualizó !!!

[NancyC1]

Woohoo! Fixed. 

[StreamerMax]

Just checked it and 🎉🎉🎉🎉 my cast is working again. It's going to be a binge weekend. 🤗

[smo987]

Does this affect a recent change where echo (speaker) devices - (multiple versions) no longer broadcast the spoken words. The only thing they do now is the announcement sound..... This seems to have started right about the same time. Thank you.

[Cristhianfox]

Solo queda esperar ...el mio esta restaurado de fabrica y aun no puedl conectarme

Debes cambiar en tu dispositivo android la fecha antes del 9 de marzo..vas a Google home vuelves a configurar y se actualiza. Una vez terminado vuelve a vambiar la fecha a la actual y puedes volver a transmitir. A mi me funciono. Suerte

[Soubin]

I did a factory reset. It helped me set the date on my phone before March 8th. Then I was able to set up Chromecast. The update was done and everything works properly even after resetting the date on my phone

[Polip]

Estuve revisando mi dispositivo ayer tratando de conectar y me aparece sin conexión. Cuando lo intento conectar ya no lo encuentra. En mi caso lo reseteé pero luego pude volver a vincularlo cambiando la fecha de mi móvil. Hay alguna respuesta para estos casos. Quisiera algo concreto para decidir si comprar otro o esperar

[Bnm1]

I’m back up and running on the devices I hadn’t reset. I’m based in the UK.

What I did.

Manually set date on my iPhone to 1st March.

chromecast audios showing as connected, could change names etc,  but couldn’t cast to them. 
Set date and time back to automatic. 
Open google home app and click on Chromecast. Shows nothing casting.

Open YTmusic, able to connect and cast.

Going to try and sort the device I had reset  tomorrow. Luckily I had 3 lying around, so could swap one out.

[Shortyken]

My chromecast received the fix about 1h ago.

One of my Chromecast Audios has come back online which is great. The other is "Online" in my Home app, but recons it's on a different WiFi network so I can't do anything with it. I'll just sit and be patient, at least I can cast to our old Receiver now. I think it's great resolving an issue for what is basically an unsupported product, although more frequent status updates would have been good, even if to say, "We are working on it." Good comms goes a long way.

[MASB]

My Chromecast Audios have arisen from the dead! Thankyou 🙂

For information, I did factory reset mine, but was able to reinstall them to Home by turning back the date on my phone.

Now, Google, all you have to do is start manufacturing Chromecast Audios again, and for anything under £100 a pop, you've a guaranteed seller.

[Ovhebesh]

Thanks a lot, updates successfully received and now it's alive 😁

[Julieta14]

Buenos días yo reinicie desde fábrica, ahora que hago ?

[Marianamulata32]

Hola. 1. Cambia la fecha de tu dispositivo al 5 de marzo..2 vas a Google home y vuelves a configurar. Una vez terminada la actualización cambias a fecha actual tu móvil y listo se hace la magia..a mi me funcionó 

[Barbicardel]

Guys, thank you, it’s working again! So happy

[sammi]

Why do you find it so difficult to keep us informed....? A simple regular update would at least let us know where we stand. But that seems to difficult.

You are not making any friends.... Indeed you are close to losing my custom in future.

[Geraldine2787]

Is the problem fix yet? We reset our Chromecast and been struggle to connect to it since Tuesday. This is hard

[Marianamulata32]

Si restablecemos la configuración de fábrica, alguien de la comunidad mencionó qué hacer. Seguí lo mismo y funcionó. Cambia la configuración, desactiva la fecha automática, cambia la fecha al 1 de marzo y luego agrega el dispositivo Chromecast a la app Inicio. Debería funcionar y no muestra el error "No pudimos autenticar tu dispositivo Chromecast". Una vez conectado el dispositivo, en unos minutos veo que Chromecast se ha actualizado y vuelve a funcionar. ¡Genial!

[klaryta]

El que no restablecí de fábrica ya funciona. Los otros dos, que los restablecí, aún no. Ojalá lo solucionen pronto!! Gracias 🙌🙌

[Marianamulata32]

El que restaursate tenes que hacer

1. Cambia la fecha en tu movil a una anterior al 9 de marzo

2. Configurar desde Google Home, una vez actualizado

3. Vuelves a cambiar la fecha EN TU MOVIL a la actual y listo puedes volver a transmitir. A mi me funcionó. Suerte

[Malenacagnani]

Gracias! Ya se actualizo solo! Así q ya estoy usando mi Chrome desde el día de hoy en argentina 

[JamesLasseter]

Looking forward to hearing from you and getting the TV working again.

[DirtyBiker]

Okay folks the fix is easy I don't know why Google has an updated their response mine is working perfectly now but I had to go through the process twice set your phone back to March 8th Go into the home app and set up new device it will find your Chromecast and apply updates once it is finished updating and rebooted set your phone back to automatic date and it will work perfectly this works even if like me you did the factory reset before Google made their announcement if it doesn't work the first time try it again until you see the update on your screen Good luck

[Kara3]

You are an absolute star 🌟 It worked first time !  Thank you so much! Google should pay you for your knowledge and expertise 👍🏻 It was driving me around the bend … hope your dirty bike behaves a good deal better than Google 😂🫣😉

[Iurie]

Salut..Mulțumesc...!

[Ricky83]

Im heavily invested on your google products, my whole house is powered by google, I know you want to kill the support to these dongles but please take in consideration that a lot of people that own this dongles are also people that own multiple other google devices and subscription.  The least you could do is allow us users to be able to use these dongles freely untill they last. 

[Pranv]

If we do factory reset, someone in the community mentioned what to do, here is what I followed the same and got success. Change in your settings , auto date off, change date to Mar 1st and then add chromecast device to Home app, it should work and doesn't give the error "we couldn'tauthenticateyour chromecast device." Once device is connected then with in few minutes i see chromecast updated and its back to working. Yay
