video issues

I hope you can understand, i'm from Italy: i'm playing with other players they all can see each others webcam but i can't see them. - "I want to receive from others:" is setted on "only video" - i don't have a webcam so i've disabled "I want to broadcast to others:" - avatar size is regular - master have setted the option firefox and chrome. I've tried to use roll20 on firefox chrome and eve edge but the problem remain, what can i do?

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 lhe 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.)
