Trim activity option seems to be missing from the latest iOS Connect app. The option was there before, but now that feature is gone from the latest app version updated July 23, 2021.
No, I'm not trying to trim an unsupported activity type....

I'm trying to trim the same cycling activity types that I used to be able to trim in the app on my iPhone. Now I can't.
Garmin, please bring back this feature!
