My Apple remote was working perfectly to turn on tv, adjust volume, and turn off Apple TV and tv. Now when I push “sleep” on remote in turns off Apple TV but doesn’t turn off tv completely. Ideas?

Hello I have the exact same issue and restarting did nothing. No changes to any settings on TV or AppleTV but just stopped working. When I try and turn the setting on it says “System Control You can’t use system control with this configuration”. Please advise. Thank you.

Try restarting your Apple TV to see if that fixes it
