My MK1 says it is syncing, and shows live data on the Garmin connect app, but in the history it only shows, for example, my very first 5 dives on the iOS app (iPhone).
my watch has over 20 dives logged on it. I’ve tried pairing unpairing repairing uninstalling reinstalling. And for some reason it just won’t do a full sync. Also possibly unrelated, my altimeter is off by nearly 2000 feet....
Watch is less than 3 months old purchased through Garmin
