Under account permissions I have full management. I need to be app admin and to create new apps when necessary. How do assign myself app admin status?

Actually, it is not ridiculous, but there is a good solution..  You may be an Account Admin, but there could be sensitive employee data or financial data that you should not be permitted to see in HR or Accounting apps.

If you would like be be listed as a Super User who has admin access to all apps in your Realm, then contact support and they can set that up for you.  They will take steps to validate your request and will require some kind of written authorization form to be signed by an officer of the company.
