Screensharing not working

I’ve been trying out Brave Talk mostly for screensharing but unfortunately, it doesn’t work most of the time. I get a message that my video has been suspended or something. When it does work the video is freezing on the remote end. Earlier this year I had exactly the same experience. Interestingly if I switch to Zoom or Google Meet it works fine so I know it’s not my internet connection or any other hardware issue… Does anyone know if there is anything I can do to fix this? Thanks!!
