Suppose two users is already connected in room. Both are sharing own video.  
If user A will start screen share, then B is not able to see the screen of A. still showing the video of A but not showing the screen of A.  
When B will refresh the page, then he can see the screen of A or If any new user will come in this group then he can see the screen of A. Existing users not able to see of screen of A.  
Following I am sharing of screen sharing code.

async function screenSharing() {  
// alert(“screenSharing”);

```
// get a screen share track
localScreen = await navigator.mediaDevices.getDisplayMedia({
  video: true,
  audio: true
});

let element = document.getElementById("local_video");
element.srcObject = localScreen;

// // create a producer for video
videoProducer = await producerTransport.produce({
  track: localScreen.getVideoTracks()[0],
  encodings: screenshareEncodings(),
  codec : device.rtpCapabilities.codecs
  .find((codec) => codec.mimeType.toLowerCase() === 'video/vp8'),
  appData: { mediaTag: 'screen-video' }
});

//create a producer for audio, if we have it
if (localScreen.getAudioTracks().length) {
  audioProducer = await producerTransport.produce({
    track: localScreen.getAudioTracks()[0],
    appData: { mediaTag: 'screen-video' }
  });
}}
```

This is just a bug in your application.

You are not consuming the new screen share `Producer` in the already connected peer. I don’t know, I cannot check your whole code.
