Hello, I've added authentication via Microsoft Graph to my web service. Everything was working fine, but at some point, I started getting an "unauthorized_client: The client does not exist or is not enabled for consumers" error when trying to authenticate. Even creating a new application led to the same result. Has anyone encountered a similar issue? Any help would be greatly appreciated. Thank you!

    Hi @Netlas Team

    This is because your app has not been registered to allow personal account logins. Go to your app, find the manifest, and change the signInAudience property value to AzureADandPersonalMicrosoftAccount and the accessTokenAcceptedVersion property value to 2.
