Hi,
Looking for some guidance on what connector this might be - we are unable to open the reference apps within the solutions they came in or if we save a copy and play them. I can access them via 'Edit' and playing them in the designer but this isn't supposed to be the way to view them. See image below of issue being experienced on 'Play' of each reference app for the MDA and Canvas managed solution.

This app isn’t opening correctly
It looks like this app isn't compliant with the latest data loss prevention policies.

Business connector: shared_office365users cannot be used with non-business connector: /providers/Microsoft.PowerApps/apis/shared_commondataservice.
