Hello @gauravsetia1991 , if you don't mind would you tell me if your screen sharing is working as expected? Like if there are two users on same channel , does the second user able to see first user's screen?

[gauravsetia1991]

Yes, for the first channel its working but when i leave the first channel and join the second one then i get the error on the user who share the screen
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'videoTrack')
at AgoraChannel.startScreenCapture

Hmm , interesting...When I tried to do that the second user was not able to see the first user's screen. Did you modify the code?

OnUserJoined, is the video surface creating?

No , I am just building one of the api examples provided to see if desktop screen share actually works.
There is this script which is being used in this api example - WebScreenShare.
Can you tell me what i need to modify to make it work?
