Cannot preview attendees from slack

I use Zoom (busines type)  just recently when creating a zoom meeting in slack, I am no longer able to preview folks that are currently in the zoom meeting.  If someone spins up a meeting and people join, zoom shows 0 people in the meeting.  

It used to be that if someone spun a zoom meeting in slack I would be able to see who is in the meeting.  This is tru for people in my organization,  no one is able to see the attendees anymore..   is there a permission setting that I need to change?
