Bought the Vivoactive because unlike the Forerunner I can use it with both running and golf. Can not get the Gof app to work properly. Can download golftracks, can start the app, but within minutes the watch face switches back to the normal clock. Tried a number of things but nothing helps: going back to the standard watch face, restarting the watch, removing the app and reinstalling it, setting the screen auto-lock to always locked or locked during activity. Also switched from GPS+ Glonass to GPS+Galileo. Nothing works. Get the feeling that the watch looses the GPS connection (out in the open golf course...?). Can hardly be true though. Anyone with a solution?
