Multi - User Sign on Issue

New Contributor III

We upgraded one of our Mac labs from Ventura to Sonoma  and I’m now having an issue with the login screen. Once a user (mobile accounts) is logged into a machine and that machine either went to the screensaver or the user locked the machine to leave. No one could login to that machine. 


-In previous versions of the macOS a new user could simple click on the switch user button at the bottom of the screen and log in. Now those options are gone.


What I've Done:

Fast User Switching is turned on. The Jamf Config also has Fast User Switching  Checked. FireVaullt is also turned off. Any ideas?

Again, only issues with Sonoma and not Ventura.
