I have an APP created in AppStore in Dev and I did move it over to QA for further testing but when I go in and try to add the App throught SiteContent - Add an App - and select the Site Provisioning Tab I get You cant add this App here and clicking on details I get another error stating
Sorry, only tenant administrators can add or give access to this app (Screenshots attached).
I have created that service apps App Management and a Subscription
Settings Service Application and the services are turned on
I have configured the APP URL
