This is still happening on 15.0 Beta (24A5264n) !! Come on APPLE FIX THIS.. I can't use any my iCloud photos as wallpapers or screen savers it just doesn't work correctly !

I am also having this problem.. I've had it on Monterey & now Ventura. I have not been able to find a solution. Restoring, Restarting Bird, Signing in and out do not resolve the problem.

So i'm noticing something.. If I uninstall Xcode, and just keep apple configurator 2 installed I am able to pair all my devices and they consistently work. That doesn't help much for development but it is making me think its something to do with Xcode.

I have this same problem -- Any Solutions other than resetting the apple tv back to defaults which only fixes it temporarily

Also having the same problem iOS 14.6 killed wifi with my asus RT-5300 and iPad 8th generation. I have never had problems on iOS 13 with WiFi. All these problems started with IOS 14. I had to return an iPad Pro because of the same problem.
