The problem still exists, just did an update to latest firmware 18.27. Did the long press to reboot. When trying to edit the runs data fields, run, trail, track virtual run etc the wtch reboots with the blue triangle. Editing other sports datafields doesn’t reboot the watch so it is run only. Is it the watch or is it garmin connect mobile. In 965 forum it occurs on IOS and android as well.
