I am following the self-guided Olympic Triathlon training plan. I can see each workout in the calendar and on the watch, but I get an error message whenever I want to see the workout details in the app.
It seems to work fine for other workouts that are not part of this plan but haven't tested it with other plans.
The same happens on two different android devices seems to be a bug on Garmin's side.
Let me know if you need additional info.
