Apple TV + continues to log out on my 2022 Roku 40"and Hisense 58" and Hisense 50"

Apple TV continues to log out on my 2022 Roku 40"and Hisense 58" and Hisense 50" and I have to re-log in.

All of the Tvs are updated to the latest firmware. The app will log back in only if a QR code is displayed.On occassion there is no QR code and any attempt to sign in with the remote fails to validate. The primary concern is why does Apple TV + continue to log out? The secondary concern is the failed password validation. Yes the password and user ID are correct). Two years ago, a community member found a workaround where you go to Guest mode viewing and add the apple app, sign in to Apple TV +(which works)and then sign out. When you go back to the normal user account and go to the Apple TV + app it opens without any issues?????

If you don't use the App for a while it logs itself back out gain. WHY???
