10/12/2021 Roku update of OS 1474->4181 and airplay update fixed both AirPlay and AppleTV problems last night. Roku3-4200X.
Thanks for the info atc98092... are you possibly aware of whether or not Apple has addressed this yet? I posted this same post to an Apple TV Support Community blog page, subcategories of Apple TV Hardware, and as a reply to a similar post on Apple TV Apps, but no responses yet. Also, are you aware if Roku can offer an older version of Apples app for download, since this is probably related to an update from Apple that was auto-installed?
Also, for everybody that reads this post and has the same issue, please make your own post describing this issue to an Apple Support Community blog, or at least post a reply to mine here... https://discussions.apple.com/thread/253237548 Hopefully if enough of us squeak the wheel, it will get greased.
And if any one of us gets a working answer somewhere else, please post that answer here for all of us.
Thanks…
Added me too to apple ticket #appletv+ issue
