My Fenix 5 won't sync any activities through Garmin Connect since a 1-2 weeks.
The watch is connect via BT to Garmin Connect and sync other data. When I press sync the blue arrows turn white and start spinning, the progress indicator starts to move but stops at "3 o'clock".
After a moment is stops the sync and the watch will then indicate "Transfer failed".
I can still sync through wifi directly from the watch without any issues.
Once I have synced my activity the sync through Garmin Connect works, until I record a new activity on the watch.
The Fenix 5 is on version 8.00 and Garmin Connect is updated on my Iphone.
Any ideas on what the problem is?
