On Android 9.0 tablet trying to share the screen return an error
navigator.mediadevice.getDisplayMedia is not a function
That's an expected behavior when the browser/OS does not support screensharing
The unexpected Result:
- The screen sharing dialog has a disabled Stop button
- New participants see an empty "shared screen" with the user picture.
- No one can share his screen until the tablet makes a refresh of his browser window
Seems that an error starting the screen sharing does not stop the already started sharing connection.
