Azure Function - Authentication - Allowed External Redirect URLs

Question

I have added acudose://easyauth.callback and https://www.microsoft.com. Only https://www.microsoft.com works. Using the post_login_redirect_url parameter sends me to the done page instead of acudose://easyauth.callback when providing the acudose://easyback.callback, but the post_login_redirect_url parameter of https://www.microsoft.com works just fine. I got through the oauth and redirect just fine to https://www.microsoft.com. This was literally working 24 hours ago. With no change to the authentication configuration. Troubleshooting complains that I don't have it configured. Additionally, at some point acudose://auth stopped working. It said that's not a valid URI. I am guessing Microsoft changed their validation as that's based on their own documentation. I honestly considering using a different service as this is ridiculous. It's no wonder Microsoft no longer calls this EasyAuth.
