Help me problem Screen Share + Camera with audio peer to peer

Hey guys,

I really need help, I have a web server in Angular and I share the screen and camera at the same time but in the onaddstream event in the app I only receive a video and an audio, below I explain the tests I did and the results:

Case 1:
Web server:
this.peerConnection.addStream(streamCam)
this.peerConnection.addStream(streamScreen)

App Android:
onaddstream:
I receive just one Stream:
Video Cam and Audio - I receive
Screen Share - No I receive


Case2
Web server:
I just reverse the order
this.peerConnection.addStream(streamScreen);
this.peerConnection.addStream(streamCam);

App Android:
onaddstream:
I receive 2 Stream :
Video Cam and Audio - I receive just Audio
Screen Share - I receive the video

Thankyou very much
