Persistent pop-up "Turn On Reactions"

Since the last zoom update, I am getting a small popup message at the top of my video window with every meeting I start. It says "Turn On Reactions 'zoom.us' has turned off Reaction effects. Click (the video icon) and select Reactions to add more impact to your gestures". It has an "x" to close the popup window. But that doesn't close it.  It only closes when I click the green video icon in the top function bar. Whether I turn Reactions on or off - the popup is still there. I don't know how to upload and image so I hope this is explanatory enough. Don't know if this is a bug, or if it's pilot error somehow. Would appreciate any tips on how to get rid of this popup!   I'm using a Macbook Pro running OS Sequoia 15.3.2.

Thanks.
