I only have stress and body battery getting stuck after i charge it, only from last patch though. Restarting it solves it, i was guessing the new patch could fix it, but i'm pretty sure it's not a problem from the birth of the 245 because i only noticed it lately, from 1 or 2 patches.
I can confirm the issue where heart rate, body battery and other features stop working right after charging.
This happens on a Window 10 machine with Garmin Express installed and the only way of fixing the issue is restarting the watch. I have tried charging the watch on a wall charger and I did not experience this issue.
