Yesterday, both the Hike app and the Walk app immediately crashed when I hit the start button. The watch was vibrating with some large numbers on the screen and nothing else until I hit the Stop. I didn't see any problems with other apps like Run, Bike, Cardio, and Strength. I reset to the default settings on both the Hike and Walk apps and this problem went away. Is there a known problem like this that Garmin is fixing in the Beta releases?
