My steps did not sync on Sat 24 April 2021, then the following weeks after, every Friday the steps don't sync. Oddly every day, other than Friday the steps sync.
I sync by connecting my watch to my MacBook Pro via cable. Syncing says successful in Garmin Express. I am not sure if it's a corrupt .fit file. With no error messages in Garmin Express I can't identify which fit file is corrupted.
I reinstalled Garmin Express. Removed the watch and added it back again in the Garmin Express. Still doesn't solve the step sync issue. The watch is running on v16.60.
Also For the Daily steps, Sat column now reads 'day 6 short'.
