Safari + WebRTC Support?

Safari has now had WebRTC support for over a year but it still is not working properly in Roll20. I loaded up Roll20's voice and video chat in Safari 12 on my MacBook and I could hear others speak, I could even send my video through my webcam, and my little blue bar above my name was lighting up when I spoke, but no one else could hear me. Is there something I can do to fix my use of voice chat in Safari? I do not have this issue when using other sites leveraging WebRTC (like Discord).  The reason I ask is because Chrome is a horrible resource hog with Roll20 and Firefox's newest version also appears to have stopped working properly for the voice/video chat. I'd really like to use Safari since it is lightweight on my MacBook and seems to work well for everything else. Happy to send along log files, etc. if that will help.

Roll20 only supports public-release Chrome and Firefox browsers.  Other browsers may or may not work and they are 'use at your own risk'. As far as Firefox and your WebRTC issues, there is a dedicated bug thread for the Roll20 WebRTC.  Please go over there and post your: Operating System Browser and Version Description of the Issue WebRTC Debug Log (Click the "Download WebRTC Debug Log" button under the settings tab) (Be aware the log only exists in yours and your players browsers up until you or they refresh. So, you'll want to download the log right after you start having issues, but before anyone refreshes, to get the most useful information.)
