Hi @Anonymous ,
I did a test for you but did not encounter a similar problem and it worked.
When I only have a sharepoint connection, it shows false.
When I have a sharepoint connection and a sql server connection, it shows true.
When I removed the sql server connection, it changed back to false.
Please check whether all premium connections are deleted and make sure you have saved and published the app.
If it still shows true, please try to create a blank app. Maybe this is not a common problem.
Best Regards,
Wearsky
