My son's Instinct is on the latest beta firmware. We went backpacking this weekend, and when we arrived at camp, we used the Resume LAter function on our watches (my F6X, his Instinct) to exit the activity for the night, to resume in the morning. Mine worked fine. His, on the other hand, kept going back into the activity's pause screen after a few minutes, and buzzing that "GPS is ready". He'd hit resume later again, and a few minutes later it's back in the activity pause screen and buzzing that "GPS is ready" again. Endless loop. Let it sit there on the pause screen for over an hour, thinking maybe it would time out and go away, but it didn't.
He ended up just saving the activity, and starting a new one the next day, so the watch wouldn't keep going back into the activity pause screen all night.
Anyone else experiencing that?
