Unable to set Notification Preferences

[Cirrus]

Can anyone advise on this please.

I have a user who turned off their notifications to go on holiday. Upon return (and us having upgraded to Madrid meantime) she has tried to turn them back on, but is getting the message "You do not have permission to modify this control". Even as admin I cannot impersonate and reset, as I also get the same message. 

Could this be an ACL or some system setting that has been changed during the upgrade, if so where do I find it?

Thanks

It looks like ACL issue only . Can you check write ACL on sys_user_preference table and check whether the user is passing the Write ACL.

You may have to review all the write operation ACL for user preference table

Vinoth, 

On closer inspection it appears the issue may well be isolated to just this user.

Issue was indeed an ACL issue, where sys_email* with a specific role was preventing other users from upating the notification field on the sys_user table
