Can't see meeting participants on desktop client Home tab

[CesarS]

I have an issue where some users at my org are not able to see participants that are joined to meetings they scheduled. Usually on the client's Home tab you can see your scheduled meetings widget. On the meetings that are underway (or 'started'), you can see small squares with initials for each joined participant. If you click on the card for the meeting, you get a pop up with more details on who is joined to the meeting. The issue is happening on Zoom Workplace version 6.3.56144. Not sure if this is a glitch or just a feature that was removed. Rebooting machines and logging out/ back into Zoom via SSO does not resolve the issue. Has anyone experienced this before?
