Entra Registration from Self-Service gives blank login window.

[sfurois]

Hi folks - working with a new jamf cloud and I've run into a problem trying to have a user follow the steps to make their device Entra compliant.  When they log into the Company Portal app (after starting the registration from Self-Service) the login screen for Entra pops up, accepts their username and password, then goes to a blank window.  We know authentication is happening because the MFA for the user kicks off but the login window is blank and does not show the numbers.  

Has anyone seen this before?  I was able to do this on a different machine two days ago.  The OS on this machine is 15.0

Update to at least macOS 15.2 (or 15.3.2 if possible, 15.4 due within the week).

Thanks for the suggestion - went to 15.3.2, verified latest Safari, but still seeing the same white screen on the MFA pop.

Oop, found the solution by reading the Best Practices tech paper https://community.jamf.com/t5/tech-thoughts/macos-conditional-access-best-practices/ba-p/273760 - I was missing the usewkwebview key.  Setting that as a plist in com.jamf.managment.jamfaad fixed me all up!
