I'm having an issue when navigating a course. What happens is that the first turn is shown, with the distance to the turn counting down as expected. I get the notification beep to turn appropriately, but then the navigation never advances to the next direction. I've inserted two pictures showing me in different locations with the directions to turn in 0 ft. The only time it advances is if I go off course and get back on, but then it does the same thing for the next turn. ClimbPro still works, and I can follow the route on the map, but I don't get any more turn alerts. This happens regardless of where I've created the route (Garmin Connect web or app, Strava, BaseCamp, etc).
What's really weird is that this doesn't always happen. I've checked all the navigation settings for each activity profile and route and don't see anything obvious. My working hypothesis is that navigation works properly when I start the route at the very beginning, and fouls up when I select the route after I've already left. Has anybody else run into this, or have any suggestions on what to do?
