Hum, I am not able to reproduce the problem, but I do see another, and video goes only one way as a result:

UnhandledPromiseRejection: InvalidModificationError: Failed to execute 'setParameters' on 'RTCRtpSender': Attempted to set RtpParameters scalabilityMode to an unsupported value for the current codecs. StackTrace:  Error: Failed to execute 'setParameters' on 'RTCRtpSender': Attempted to set RtpParameters scalabilityMode to an unsupported value for the current codecs.

@jallamsetty1 Can you PTAL? Just enable E2EE and check the browser JS console for these logs.

Yep I was looking into it yesterday. Damian and I reproduced the same issue as you. The error is a red herring, it didn't have any impact on the send video. On the receiver side though when the video is not being rendered, it is being decoded but just not rendered as the browser doesn't fire the canplaythrough event. Will continue debugging it today.
