Cancelling registrants status does *not* seem to work

Description

Sorry to ask this yet again – but all previous such topics have not shown an answer/resolution (all the while being closed).

So, here goes again:

  • I register a new registrant to a (recurring) webinar; all good: a call to retrieve registrant details shows everything’s in shape;
  • I place a call update the status to “cancel” (as per Zoom Meeting API); the response status is 204; all good seemingly;
  • a subsequent call to show registrant details and status shows him as “approved”.

Error?
No specific error message – except the status remains unchanged.

How To Reproduce
as per the steps above… log output:

Any comments? Obvious omission? Help much appreciated.
