I only have 1 Apple TV that supports this feature. The others are not new enough. It works with my iPhone 12 on this ATV, but not with my iPad. The iPad is 4 years old. I have not chased down if it is too old to do it. Both have OS 17.1 or higher.

Seems to require some really new hardware.

iPhone app “MapMyTracks”.

I have the same issue. My watch is the same age, more or less.

I clean my watch, protector, and band ends with rubbing alcohol once a month. I remove the band and clean the slot that the band slides in.

I will try cleaning under the crown with a slip of paper.
