iOS Sign in with Apple error: signup not completed

I can’t get Sign in with Apple to work for my iOS app. I followed the instructions on https://appwrite.io/integrations/oauth-apple very closely and multiple times but every time I try to sign in/up I get the error „sign up not completed“.

The only thing i did differently was that I didn’t set my bundle id as the unique identifier of the service id because it told me that its not available.

Somehow I doubt that that’s the issue since Apple doesn’t mention that it has to have anything to do with your bundle id.

What else could be wrong?

I created the service id, configured the appwrite.io domain and the redirect url, I created the key, entered all the values to appretiert oauth setup (every value copy pasted so no room for error) I tried it with having the team id in front of my app id because someone in the forum suggested it but also with no luck.

I also added the url scheme to my app and the scene delegate.

I’m really stuck. I hope anyone has an idea.
