I'm on BC20 Cloud with my Database hosted by a 3rd party, not MS. When I go to the extension marketplace to install an app I get an error (even though I have super user admin rights):
Installation of extensions from the marketplace is not supported for your system configuration. For more information, see https://docs.microsoft.com/en-us/dynamics365/business-central/ui-extensions
Is the extension of apps only allowed if the DB is hosted by MS? Why is that the case? It creates massive integration headaches for non-MS hosted DB's when installs can't take place and let the apps properly talk to my database.
