After starting a strength training activity on my Lily, it will track reps and rest for maybe one or two sets, then the watch seems to crash (goes to screen with Garmin triangle on it for 20 seconds or so) then shows the "activity complete" screen where you can choose to save or discard. Even if I choose instead to continue the activity from this screen, it no longer continues to track reps and rest periods and instead keeps crashing.
This is the main activity app I use on any Garmin device, please advise how I can fix this as it is having a significant impact on the usefulness of my device!
