Raise hands no longer seems to work (macOS)

Hello

In the last few days the raise hands call in the macOS SDK has ceased to function - lower hands still appears fine, but raise hand returns SDK error 4 for a remote user and SDK error 5 for when you try and raise your own hands. I’ve noticed that in the newest zoom client the raise hand button has moved into “reactions” and I’m wondering if something has also changed server side.

And for clarity, to raise a hand for a user I am calling:
[MEETING_ACTION_CONTROLLER raiseHand: true UserID:userID];

where userID is a known good user ID (and the same ID works to lower a user’s hand)

Thanks

Richard
