You must Add reset permissions to application level via UX
Most times your support does any work on my behalf the permissions get messed up and then have to recontact support to set permissions to application level. This is an extremely frustrating restriction on the user and is making me consider to switch hosts. I really suggest you add a self serve option to the UX sooner rather than later.
You're wrong, Paul, this button is not resetting permissions at application level.
The constant messing of file ownership has been an ongoing problem on CW for years.
But FYI - there is a button for you to manually reset ownership/permissions yourself.
In the specific application's Application Management Dashboard > Application Settings there is a button for Reset Permission. (Support should have been able to tell you this - it's required A LOT.)
