I have a new Descent MK1. I pair it with my iphoneX on the latest iOS (11.2.6), and it pairs with no issues. It usually will sync that first time successfully with Connect Mobile.
After that, it never syncs successfully. It is paired just fine. It shows connected in the Connect Mobile app, and notifications come in with no problem. It just never syncs. I manually initiate one through app, and it starts, but then fails after 10-15 seconds or so every time. The automated syncs all fail, too.
Looking at the sync logs on the device, it always shows some variation of: "Error Domain=GCMSyncErrorDomain Code=2 'Device connection error'"
The only way I get a sync to work is to connect directly to my Mac and do it through Garmin Express.
I have factory reset the watch multiple times. I have re-installed Connect Mobile multiple times. I have even tried creating a different Garmin account from scratch and connecting in that way.
In all cases, the pairing works fine, but syncs stop working after that first one or two syncs.
Any help is much appreciated....I am very frustrated that I bought a high-end device that cannot sync with any success (like just about another other non-garmin brand device does).
thanks!
