Greetings, the watch interfaces I downloaded to my Garmin Fenix 6 watch are after new updates or after a while I am facing this problem. I tried everything to make it go away, but it still does not work.
Looks like it tells you need to purchase a Pro Code for the 3rd party app. If you are not willing to pay for it, uninstall it. If you want it, pay to get it unlocked.
