The Forerunner 220 fails to update. The Garmin Express recognizes the device and discovers available updates. When attempting to install the updates the processing takes a long time after which the red topbar with a message "There was an error syncing with Garmin Connect" is displayed. The same repeats after reconnecting the device or restarting Garmin Connect.
I tried to restart the Forerunner, selected "Restore Defaults" on the device - it didn't help.
