I know this is (sadly) a common problem but there is no solution that works for me right now. It has happened a couple of weeks ago, but then reinstalling the Garmin Connect app helped. Today, it's different. Notifications stopped working on m vivoactive 4S, and they didn'd come back after multiple restarts, deleting the cache, the data and even reinstalling the app. They are still working on my vivosport, though!
Is there anything else I could try short of resetting the watch? (which I would hate because loosing all settings and Garmin Pay is not very customer friendly)
Thanks for any help.
