Thanks for reaching out. Let's sort this out.
A few questions: Does your Harman/Kardon Citation 100 have a built-in Chromecast or do you have a separate Chromecast dongle connected to it? What is the make and model of your phone? Could you share a photo of the issue? Please reboot your speaker, mobile device, and Wi-Fi router. Also, make sure your phone is connected to the same network as your speaker. Using a different mobile device might also help.
Keep me posted.
I have four different citation models 100s and ones there are all basically paperweights because of this now. I moved and now everything is super pissed. I was able to get one of them working on an old router that it was previously connected to. So I'm seriously running an old separate router hoping to connect to Old devices because Google doesn't allow things to connect anymore. Thanks Google! I have every Nexus from the one on and I might stop buying your stuff if Google takes it upon themself to turn things off.. I probably have 40 smart devices and can only get four of them to work now.🤬
Hey there Erico,
I'm sorry about the delayed response on this, but following up on Jennifer's reply, do these devices have Chromecast built-in? What is their Cast firmware version? I would double-check that their firmware is up-to-date, as well as make sure your Google Home app is up-to-date. If you're still running into issues, you may find more success by reaching out to Harman Kardon support, as they may be able to troubleshoot the devices further.
I look forward to your reply, and if you had any other questions, please let us know.
