Notification on Apple TV
I have a red Number 1 that has appeared next to "Users & Account" on my apple tv settings menu. I have tried everything I can think of to get rid of it. Restart, Reset, Sign Out & In. What is this and how do I get rid of it?
If you go to Settings﹥Users and Accounts﹥, then you may find that it wants to update user settings or reconnect with iCloud, or agree with terms and conditions. It may ask to hold your iPhone or iPad (if you have it) close to it, to complete the process.
Verify that you have updated all devices to the latest version. With Apple TV on tvOS 16.5, you may want to bring any iPhone or iPad to version 16.5 as well. Update your iPhone or iPad - Apple Support
