A few days ago there was an update version (25.11), fixing a problem with saving golf rounds and scores, but since I've updated my watch, it almost daily looses connection to my Samsung. I recognize it because the time is 1 hour in the future, otherwise I wouldn't recognize it.
It take some time to get the connection running again. This time I had to remove the epix from garmin connect an link it again.
Synchronization takes minutes since the software update, not seconds.
