As of 1 Feb 2025:
- watch doesn't display some data (says no data)
 - can't use the walking activity as it restarts
 - sleep mode turns on even during the day time
 - top button doesn't work properly
 - step count out of whack - increases and decreases randomly
 
there are probably other issues but these are the ones I've experienced for now.
I've done a factory settings reset and unpaired my watch from device. Didn't work
