I've tried to record multisport activity and found that ui is... questionable:
I've done a warm up run, did some strength exercies in local calisthenics park.
Next I wanted to switch back for cool down run home.
How convinient - there is "Return to Run" menu, I could use it instead of going down to "Change sport" and picking sport there.
oops, last 30 minutes of different exercises was discarded without any confirmation.
No idea, why you've edited number of reps - you were running all this time.
Dear Garmin,
Could you please rename this menu to something like "Cancel {}"(current exercise), instead of "Return to {}"(previous exercise).
