Hi!
We have created a SharePoint-app and have installed it successfully in many O365+SP environments. However, we have encountered a problem in two O365 environments. In those cases we are able to add the SP app to the App Catalog normally, but we are unable to add it to any site collections, as the app is not shown when we try to add an app from site contents.
The account we use is the owner of the App Catalog and site collection admin. We have tried removing the app and adding it again to the App Catalog, but this does not help.
Has anyone else encountered this problem, and how have you solved it?
