Recently I've started having a problem with my Garmin Fenis 5x plus where the battery drains overnight on three quarters of a charge and during a manual sync the app never completes a sync (iPhone X running latest iOS and app). Still digging into the details but if anyone has any insight or recommendations, I'd appreciate the insight.
So just a bit of an update. I've tried removing and reinstalling Garmin Connect from my phone. Same result. I've tried removing my Fenix 5 from Garmin Connect and reconnect. Same result. I get a green dot in Garmin Connect but it never completes steps and data sync.
