Hi,
I'm having the problem with my Forerunner 735XT that I can't sync it with the mobile app on Android or the Garmin Express on my Laptop. So I can't install any updates, courses, workouts, widgets etc. but recorded activities are uploaded without any problems.
I restored my watch to default settings (several times) and re-installed the apps without any success, the problem is still the same. Had a look at the error log file on the watch but it didn't help.
Can anyone please help??
