Hi @Nuveda , to fix this you may need to configure a signature hash for the app to get it to work. You can find more info here: https://github.com/AzureAD/microsoft-authentication-library-for-android/issues/1550#issuecomment-962629868
In the case that this doesn't work please let me know and I'll open a free support ticket for you.
If this answer helped you please mark it as "Verified" so other users can reference it.
Thank you,
James
