During my recent swims, when I start indoor swimming. It only records the initial laps, and then the screen freezes.
After stopping the activity and switching to the electronic compass.
I found that the compass was completely frozen and unable to distinguish directions.
I tried turn off the watch and restarting it.
Then resuming the indoor swimming activity, everything works normally again without any stops.
The next day, when I tried indoor swimming again, the same issue occurred.
These issues had never happened before.
In the same pool with the same watch, which I've been using for a year without any problems.
Could this be caused by the recent firmware update?
