I made my first ride with a loaded course since upgrading to firmware 20.19. The turn popups always came in time but every time the popup kept beeing on the screen after I made the turn. The blue triangle for my current position showed I'm perfectly on the course and the turn was behind me but the Edge insisted I still have to make the turn. It even did increase the distance to turn again after it went down correctly to 0. Only when the next turn was due the old popup did vanish or when I rode for some minutes the popup closed automatically.
