Bumping this up again to gain awareness how frustrating it is not being able to edit these profiles. Made also a wish.
There are scenarios like iOS 13 launch, where it looked like some functions or API calls got deprecated or even new mandatory windows got added. So we haven't been able to activate our devices and have been forced to create a new profile from scratch
I can imagine a scenario like this:
In SM we should be able to edit the settings and in the background SM can create a new version of the profile and push it to Apple Business Manager. (According to dashboard, Apple doesn't allow the deletion of DEP profiles)
