I'm testing mobile apps.
Have created an AuthenticationPolicy and made no modifications so all "AllowBasicAuth<protocols>" are disabled and assigned the policy to my test account.
I'm still able to login on my iPhone with the native e-mail client and with my Samsung Note with GMail app.
But when I go to the Azure Portal to check the login activity I only see the logon from the GMail app, the iPhone logon is nowhere to be found.
And in the logging of the GMail app, the Authentication Details tab is empty.
So how can we see that Modern Authentication is working?
Yes, you can say: "because the apps are working fine", but I want to be able to see it in the logging that it is Modern Authentication, that the policy is working.
For both the iPhone as the Google Android devices.
