Hi avis22,
We see you're posting from the About watchOS 9 Updates page. Have you tried restarting your watch to see if the issue persists? This can sometimes help with minor software issues. Here's some information from the Use gym equipment with Apple Watch resource that might be helpful:
"Pair your Apple Watch Ultra with gym equipment
- Check if the equipment is compatible—youʼll see “Connects to Apple Watch” or “Connect to Apple Watch” on the equipment.
- Make sure your watch is set to detect gym equipment—open the Settings app
on your Apple Watch Ultra, tap Workout, then turn on Detect Gym Equipment. - Hold your Apple Watch Ultra within a few centimeters of the contactless reader on the gym equipment, with the display facing the reader.
- A gentle tap and beep confirm that your Apple Watch Ultra is paired.
If Detect Gym Equipment is off in Settings on your Apple Watch Ultra, open the Workout app
, then hold your Apple Watch Ultra near the contactless reader on the gym equipment, with the display facing the reader."
