Authorize page shows 'Invalid redirect_uri'

Hi,

i'm trying to implement the Sign in with apple feature to our web login.
Code Block
I configured the App ID and Service ID and added the return Url "https://example-app.com/redirect".

If i request the following authorize endpoint
https://appleid.apple.com/auth/authorize?response_mode=form_post&response_type=code&client_id=com.sentbe.login.Apple&scope=email&state=<state>&redirect_uri=https://sentbe-f3db4.firebaseapp.com/__/auth/handler
i constantly get the error message "invalid_request. Invalid redirect_uri."
Tried a lot of things. Using an uri under the registered domain, used this uri url encoded and not encoded, short uri, long uri, etc.
The uri i used in the link, ist the same i configured in the service ID configuration backend.
I have no idea whats wrong here. Maybe someone had the same problems and any solution for me.
Thanks a lot!

Client ID(Service ID):
Code Block
com.sentbe.login.Apple

Redirect URI:
Code Block
https://sentbe-f3db4.firebaseapp.com/__/auth/handler

I'm getting exactly the same issue @Apple
I also registered the return URLs in Website Urls
We have the same problem here, the new Service ID does not work: invalid_client

The old one works like a charm (we did not delete it though)

We also cannot use newly added redirect URIs to old Service IDs, invalid_redirect_uri

Looks like something does not get updated correctly on the Apple side
Yes. It worked for a personal account, but I changed it to an office account, but it didn't work.

How can fix it?

I'm getting exactly the same issue!!! @Apple

we have more than 48 hours with the same issue
