Hello,
I did not find anything online regarding this issue yet, but its been around for a while now, at least for me.
On the Garmin Connect app, whenever I change a data screen in my "trail run" activity (switch a screen from 5 to 6 fields for example) the loader briefly shows up and then nothing changes : still 5 fields.
But what I discovered the hard way is that it AWLAYS overrides an existing data screen in my "run" activity with the screen I tried to modify in "trail run" AND adds this same screen as a new screen, meaning I end up with 2 unwanted screens in "run".
If I try to do it 3 times it replaces 3 screens and adds 3 more.
It works perfectly when I do it on the watch, but come on…
I am honestly so tired of the UX of the Garmin Connect App.
Having to keep a memo of each activity screen as a backup for when (not "if") there is a bug is tiring.
