I recently noticed that random video recommendations were showing up at the end of my embedded YouTube videos. This is apparently a known thing, and the way to correct it and keep YouTube only showing videos from your own channel, as of 2023, is to add &rel=0 at the end of the video URL.
However it looks like the “&rel=0” video suffix isn’t honored in the Palm version of Open edX. Does anyone know a workaround for this?
