I could do it!...
The solution is to pause the training (go to Garmin Coach - then the three dots on the top right, choose "Pause"). Then resume it immediately and the missed training was there!... Hope…
I believe, you do not need to reschedule missed workouts of a coach plan. Simply pause or reschedule the future workouts, and start the missed workout directly on the watch:
Didn't work for me. Once it is marked skipped on the plan and your watch is synced, I can't move it on the calendar and I can't select it from the workplace. Also the work out plan progresses…
Yes, that worked! Pause/resume training plan automatically took my missed long run from yesterday and scheduled it for tomorrow. I could then reschedule it for today. Brilliant. It also changed the week from a 4 to a 3 session week though. Need to test if I can manually add an easy run now.
Thank you this just worked great. After pausing then resuming, yesterday's missed event showed up on the schedule for tomorrow, and I was then able to move it to today and off I went. It's a strange, glitchy workaround of this - hopefully Garmin can fix a more logical option soon.
