I am using a FR630, with an Sony Xperia X, and the watch no longer auto-sync's with my phone when opening the Garmin Connect app. If I open the app, it shows that the watch is connected, has the green dot, but just doesn't sync. Even if I press the sync/refresh button on the top right, it will not sync.
The only way I am able to trigger the sync'ing, is by removing the device and re-pairing.
Any Idea's?
Garmin Connect version 4.2.2
GR630 version 7.5
