I just fixed mine! Someone said to change the date in your phone
settings to before 9 Mar 2025. Then go in to Google home app and setup
your chromecast. Then change the phone date back when the setup is
complete. Mine actually did some kind of update...
I have not factory reset my 2nd gen. Google playstore is only up to
3.30.1.5. Tried to re setup and get error. Could not authenticate my
chrome cast device. WTHeck now?
