4k Apple TV Remote suddenly not responding
I have two 4k apple TV remotes that suddenly stopped working - at the same time. When the first one stopped I tried recharging it. The next morning the second one stopped working on a different box/tv. Both are older 4k boxes and both have the touch pad. Both boxes are running tvOS 18.3. I tried pairing these to the boxes again but no response. Both boxes do work with alternate remotes or the remote app on the iPhone.
Conversely, I have another even older box (1080p) with an older touch pad remote - running tvOS 18.3. This box and remote seems to work fine.
Since autoupdate is on for all these boxes, I can’t tell if an update has recently been run to effect these remotes. Please help.
