Please do post when you hear back. I’m developing an app using NSPersistentCloudKitContainer, and while I don’t see this happening, I have a small test data size (for now) and am very interested in what’s causing this and if it’s fixed. I’d hate to release the app and see this in the wild. Thanks for all the updates.

I'm seeing the same "Account Temporarily Unavailable" (1028/2011); "Account temporarily unavailable due to bad or missing auth token" problem. I'm hoping this can be fixed sever-side, as I'm blocked right now and don't want to wait for 2 more weeks for a fix.

That is great to hear! Does this work with automatic migrations or does it require a new model version?
