I really don't know if this is the place, couldn't find any other option of contacting Garmin...
But, since the last update I cannot edit my workouts on garmin connect mobile anymore.
I can push the button 'change workout', it opens perfect, but as soon as I press one of the steps in the workout, the app shuts down.
This seems to happen only to already existing workouts, if I make a new one, the problem isn't there. ....
I hope this issue gets fixed soon....
