I've used the Vivoactive 3 for almost a week now synced with my Iphone X. But this morning the app crashed when I tried to open it. I tried to reinstall the app and unpair the Garmin watch with the Iphone. Then I relaised the app was workin when the watch was not connected. As soon as I paired the watch with the Iphone again the app crashed. If I turn off blutooth the app starts fine. Anyone knows how to fix this?
