Webrtc MacOS app sending stereo but playing dual mono in browser or left channel only in Mac App

Hello everyone. Thanks for your help in advance. I’m having this bug with my app. Chrome to Chrome works fine. But when I stream from our Mac App, I set it to stereo for the SDP and it says it’s stereo but I’m only getting dual mono in a browser or in a Mac App receiver it plays only on the left channel. I don’t know how to force stereo on the subscriber side… any help would be greatly appreciated!
