Virtual Background is not displayed to user even when one applied, but the participants can see that

I have integrated zoom meeting sdk and currently using it in an iframe. The browser on which we are working on is “Chrome”. I followed “GitHub - zoom/meetingsdk-javascript-sample: Use the Zoom Meeting SDK in (vanilla) JavaScript” provided by Zoom. When I try to apply Zoom virtual background. Firstly, i see a circle shape on the Background tab which is a unique behavior. Secondly, when I select a background. I cannot see the updated UI on zoom. I am using zoom ‘2.13.0’ version. I am attaching a screenshot for your kind reference as well.

for Virtual Background you need to enable SharedArrayBuffer

Hi Jurgen, thank you for your kind reply. I have already added “origin-trial” in meta tag.

to proof if it’s a mac problem, you could try the ‘normal’ web version

try the zoom non SDK web version on
