No ad-hoc join button on Poly home screen

Did this in my Zoom Rooms Meeting settings:

Support Interoperability for Zoom Rooms    (Enabled)

  Show ad-hoc join button on home screen  (for Teams, Meet & Webex)

Home screen still has only the main 3 icons: New Meeting, Join, Share Content

Verified device firmware/software all up to date and has been rebooted.
