The calendar view used to let you edit scheduled imported workouts. As recently, it seems like this has been removed/patched. This increased the friction a lot in customising these imported workouts.
For example, workouts from Runna frequently have "conversational" pace blocks as a description, with a pace ceiling. Garmin connect will interpret this as a pace target, so I found it very useful to edit this to actually be a heart rate zone 2 target.
I now have to:
1) Duplicate the imported workout
2) Delete original imported workout
3) Rename (so it doesn't have prefix of "Copy of")
4) Readd to calendar so it gets suggested as daily workout
5) Link activity upon completion within Runna as it would not pick it up automatically anymore
These are all steps I never had to do prior to this change. I'm unsure if this existed as an oversight bug, but it was very much a welcomed feature.
