I can confirm that the workarounds posted on Reddit and elsewhere will indeed restore Gen2 casting from Android devices and Chrome browser (sorry, iPhone users). I had mine back up 'n running by Monday morning. Not perfect, but for those who are impatient (and reasonably tech-savvy), it's a viable option until Google issues a proper security certificate fix.

[RomyRivercold]

I did it, but only made my Chromecast setup, but I can't still cast anything from any app. Didn't the firmware update released already? 

[johnnyzero2]

Did you make sure to revert your phone's date/time setting to Auto?

[Brad54]

Thanks in advance.

I also did the factory reset as part of troubleshooting. Please tell us that there is a way to fix them.

Puedes volver a configurar cambiando la fecha del celular con el cual configuras y transmite contenidos al chromecast: cambia la fecha en tu celular al 7 de marzo, luego vuelves a realizar los pasos que normalmente harías para configurarlo, luego déjalo así nomas, hasta que los inoperantes responsables de todo este problema nos envíen nuevas instrucciones, por lo pronto habrás logrado configurar tu chromcast y verás los lindos paisajes de G. home. 

Aun así luego de hacer esto, chequea en la app de G. home la última actualización, sabrá Dios que nuevo parche habrán inventado tratando de arreglar el cagadon que hicieron.

[Sukanya7279]

When will the issue get resolved.

[YaraNam]

Is Wednesday,  how long will this take?

[Jzflsrt]

At the time I noticed that the Chromecast wasn't casting, I performed a Factory reset followed by resetting the modem. Later I realized that this was an issue with the Chromecast unit. I will be needing help with this please.

[hansa26d]

Same issue with me
