Firebase Auth and Microsoft provider

[KlausJokisuo]

We have a Flutter application that uses Firebase Auth with Microsoft provider. Problem is that the redirect URL assigned in Azure is always incorrect.

Usually I just assign the firebase Auth handler url in Azure and it works (at least on react application) but for Android and iOS I get redirect url mismatch error and the request url is something like this https://firebase-project-id--iskjd1727-idkdll-kdkdnd888.web-apps.com

Then random string after the id changes often and is not static.

Any ideas what is going on?
