Hello, we are planning to migrate an app that uses iCloud documents to store some documents that the user can upload/download and modify. In the official overview of App Transfer here, there are information related to CloudKit Containers and KVS but nothing related to iCloud Documents. The content of iCloud Documents is accessed using FileManager.default.url(forUbiquityContainerIdentifier: containerID) where the containerID has the form iCloud.com.things.things, even if in the official documentation it is written that the identifier must be prefixed with the Team ID. With this ID the storage works properly and we never experienced problems. Do you know if migrating an app with this functionality can be problematic? Do you know if the Team ID is somehow used even if not explicitly passed in the call to the function? Thank you and have a nice day!

Hello, after migrating one of our apps, APP, from the one developer account to another, we are experiencing an issue with provisioning profiles. In the provisioning profile of APP (com.SOME.APP), we have a wrong value for the com.apple.developer.ubiquity-kvstore-identifier key used for iCloud KVS. The value is OLDTEAMID.com.SOME.APP.EXTENSION while it should be just OLDTEAMID.com.SOME.APP. The previous value must be instead present in the provisioning profiles for the EXTENSION (OLDTEAMID.com.SOME.APP.EXTENSION) for the com.apple.developer.ubiquity-kvstore-identifier key. Please let me know if you know something about this issue. This is blocking us from releasing the application. Thank you!
