Intune is restricting few users while signing into Microsoft using oauth from a third party app

Question

We have used Microsoft OAuth to enable Microsoft login in our mobile application developed using react-native. The package used for OAuth is https://www.npmjs.com/package/react-native-app-auth.

But a few Microsoft users are being blocked with the above alerts from Intune. Other users are able to log in without any problem.

Thanks in advance for any help.

@Ramya Reddy Thanks for posting in our Q&A.

For this issue, it seems that there is a conditional access policy to block the access. To clarify this issue, we appreciate your help to collect some information:

1.Please check if there is a conditional access policy deployed to your user. If yes, please check if the setting "Require app protection policy" is select under "Grant" in this policy.

2.Based on my research, app protection policies' supported apps are listed in the following article:

Your app is not listed in this list.

If there is anything update, feel free to let us know.
