@Jaxdu, this issue persecuted my watch for a very loong time, firmware after firmware; then, with the “old” firmware 2.40.44, the issue seemed to be solved.
However, with all the firmware releases between 2.40.44 and 2.48.16, the issue came back, so I always downgraded the watch to 2.40.44.
Now, actually for the last 2 weeks, my watch is running with firmware 2.48.16 without problems ().
Once I’ve installed the latest firmware, I’ve only proceed with a watch soft reset, as usually suggested: give it a try!
