The left part of the zoom remote control works. The right part of the remote control does not work

There is a bug in the remote control of zoom this week, I am a teacher. When I use zoom to teach students to learn, they use the remote control part of the left side of my shield. But there is a bug in the remote control function on the right, and the students cannot control the right part. I have updated or reinstalled, and I have also tested with different devices, but the result is still not working, please fix this bug in time, thank you very much.
