@davidzhao I have a problem while setting up livekit in my app. I am using the latest version of livekit-client and sdk "livekit-client": "^2.13.0", "livekit-server-sdk": "^2.12.0".

I have set up my token api and it is working and generating tokens for participants.

Also, I have set up publishing and subscribing for the participants and the log on the console for the participant shows that publishing of tracks or video and audio are successful from one participant, likewise the receiving participant logs successful subscribing.

Now the problem is that, no video or audio is received from the subscribing end, even when it showed successfully subscribed in the console log. What is the problem please. I need you assistance here.

Thanks for your anticipated response.
