Any Hybrid Azure AD Joined computers these 2 users sign into, they can use a password just fine but when they try to use a Windows Hello for Business PIN they get the following message "This option is temporarily unavailable. For now, please use a different method to sign in".
These 2 users can sign into any Azure AD Joined computers using a Windows Hello for Business PIN with no issues.
All other users can sign into Azure AD Joined and Hybrid Azure AD Joined computers using a Windows Hello for Business Pin.
So, it's only these 2 users and it's only on Hybrid Azure AD Joined computers.
I don't want to try to delete and re-create these users as one of the users is me and the other is my business partner.
