Of late, I have experience twice my running activities not auto-sync (which I have activated auto-sync, and both WIFI and Phone are connected ) from my FR965 to Garmin Connect mobile apps. Firmware version 4.19.
I have no choice but manually sync from 965 > Connectivity> Phone or WIFI, then slide down Garmin Connect, only activities able to upload to GC.
May I know what is the issue? Is this only happen to me?
