F1 license user is not recognized in person and group field

Hi ,

I have a f1 license user, and he is not recognized in person and group field.

When i click on  the user, nothing popups i.e we dont get to see the hover card.

In our azure ad i see that UPN is set to username@domain.name

and email is blank.

I guess the reason is that F1 license users dont have email
