Video SDK UI Toolkit hides video section on mobile view for host in Next.js app

Hi Zoom Community,

I’m using the Zoom Video SDK UI Toolkit in my Next.js application. Everything works perfectly in desktop view, but I’m facing an issue on mobile view:

When I switch to mobile view (using Chrome DevTools or an actual mobile device), the video section for the host is hidden if there is only one participant.

However, when two participants are connected (host and participant both share their screens), the video section does not hide — it displays correctly.

I am not overriding any CSS properties of the SDK UI Toolkit in my app. I’m simply rendering the meeting inside a div with the sessionContainer ID.

Has anyone faced this issue? Any ideas to fix it?

Thanks in advance!
