Changes to participants of scheduled meetings are not applied

Zoom Workplace (7.0.5, Win)

Hi all.

I have had issues this week adding or removing participants to all scheduled occurrences of my meetings through the Workplace app.
Everything looks as it should as I edit, I hit save, the expected Chrome calendar tab pops up (GCal integration), but the meetings remain unchanged in Zoom and GCal.

I note that making changes via the web portal works as expected, without issue.

We are just back from holidays, so this issue is only somewhat recent.


Thanks to all for your help, or for reading.
