I have seem to run into an issue with permissions and app creation.
I created a new app via the Fibery dashboard for my personal use called “Personal Notes”, which only gave me access to the app as a Creator. Everyone else in my team had “No Access” set. This was working as expected.
Another team member created their own app, also called “Personal Notes”. When they “created” the application, they were redirected to my application and given permissions as a creator for the application. They were then also able to change the permissions of my app and lock me out of it without my approval.
