We are encountering an issue with the Apple ID login in my Ionic Capacitor app. Despite completing all the necessary setups in the Apple Developer Console and adding the client ID, client secret, Apple team ID, and key ID, we are unable to sign in using Apple. Every time we attempt to log in, an error screen is displayed.
We have attached a screenshot of the error screen for your reference.
In the interest of time, we would appreciate if we could get on a quick call with Auth rep to resolve this on priority! Could you please provide a suitable time when you are available?
It looks like the screenshot mentioned did not get uploaded unfortunately, as I cannot see it, but one common error message in these situations would be " Sign-up not completed", which would be caused by configuration issues and mismatch between the IDs/secrets.
I recommend looking over our Knowledge Article covering Native sign-in with Apple ID fails with “Sign-up not completed” and follow the steps outlined. Hopefully these will resolve the issue at hand, but let us know if you continue encountering the same error message.
