is the user you’re trying to delete created at runtime?
If no (= the user is created by AS MpUserX configuration file), then this user cannot be deleted by MpUserXManagerUI.
Okay, any status / errors at the MpUserManagerXUIConnect?
And, just to be sure - I’m not sure if the lists are updated on the fly, so anything changes if disabling ManagerUI and re-enabling (enable = FALSE + enable = TRUE)?
No errors or status,status is always at idle for MpUserManagerXUIConnect. Not sure about the reseting the FB again, but i have given multiple warm starts but the list seems to be the same
Okay, if you’ve already rebooted then it makes no sense resetting the FB again.
Right now, I don’t see any easy explanation for the behavior (by just looking into the documentation, as I have no ready test environment available right now).
So if no more ideas coming up here in the community, I would recommend to contact your local support for further investigation.
