After having ongoing problems with my va3, I sold it and got a fenix 5.
The fenix, while an all round better device in most aspects, is almost useless with golf.
I reboot the device before each game. After a few shots, I notice I'm back at the watch face. So I start the golf app again and it offers to resume the round.
The problem is that while it keeps track of the score it loses the shot data which is the most important reason for having a gps golf device!
I've tried factory resetting the device. I've tried deleting and reinstalling the golf app. This problem seems to happen every time.
My gfs 5s is fine. No problems at all.
I see there's a post in the 5x forum for people having problems with the app crashing too.
Garmin, you need to sort this out. The device is a premium and expensive item and is kind of not fit for purpose.
