Anyone complaining here ever considered that app developers/app companies might be at fault for not updating their apps to support Android 12 on Google TV? or is it just easier to blame Google :p
And by all means, Google does some dumb stuff at times, but quite often app developers of those big apps or their companies are just as bad or worse...
Why are you wasting time with this?
If it was widespread, there would already be threads about that with several hundreds/thousands of votes and comments.
Just factory reset your Chromecast and be done with it.
What's broken about it?
