I'm a new developer and I'm trying to unpublish my app that is in "Open test" mode, but "unpublish" button is disabled. Is there any problem with "Open test" mode. Help me please
Solution
You can try this:
Open Publishing Overview tab
If Managed Publishing turned on, turn it off by clicking the 'Manage' button
Now you can open Advanced Settings and unpublish the app choosing the 'Unpublished' switch
Save changes by selecting the button on right bottom corner
