I'm using aws cognito for authentication in my app, and added the "Sign in with apple" identity provider. Everything worked as expected, and then a few days ago the sign in stopped working - displaying "Sign Up Not Completed" error.
I tried recreating the Private Key, and also recreating the Service Identifier. Nothing helped.
Anyone experiencing anything like this?
Solved - we were using a custom domain in AWS cognito, and had the wrong value in the Service Identifier
hey i am experiencing exactly same issue with my app connected with cognition and custom domain. do you mind elaborating more on how you fixed it?
Hi @chloeminkyung I just stumbled on this post also having the same issue.
I got my app to work from this information by asking ChatGPT, haha. Basically there's an Apple Service ID, along with the Team ID, Key ID and Private key. My Apple Service ID did not match the IDENTIFIER inside Apple's Certificates, Identifiers & Profiles with the Service IDs from the drop down in the top right of the page.
Hope this helps!
