I have a Forerunner 220 and an activity from this morning that won't sync - it's like it thinks it already synced. I use Bluetooth to Garmin Connect on my Samsung Galaxy S5. The watch connects, and I can see in Garmin Connect that it connects and says "Sync Complete" within 1 second.
I have rebooted the phone multiple times.
I have turned Bluetooth off and back on on the watch.
I have started and ended another activity on the watch, and watched it sync successfully.
I've unpaired the device and re-paired it.
This one seems to be marked as already synced, and I can't find any way to force it to re-do.
Any help?
