Forerunner 255 Music 20.29 - error syncing with Garmin Connect

I  am getting an error syncing with Garmin Connect on Garmin Express at the moment.

I followed this instructions - https://support.garmin.com/en-HK/?faq=GiLICKFtvE1nV5uq9diX89 but no hope.

I even deleted the activity files from the Garmin device but also no hope. Anyone has any idea how to fix this issue?

  • The issue has been fixed by the following steps:

    1 - Remove the device from Garmin Express

    2 - Unistall Garmin Express

    3 - On Mac, Finder > Go > Library > Application Support and Remove the entire Garmin folder

    4 - Reinstlal Garmin Express and follow the instructions to add the device.

    5 - Voilà!!
