hi, i just installed ubuntu 20.04 LTS. I am not running any extensions or add-ons, just default settings. I can't play any youtube video that is considered 'live'. I can watch any other video on youtube, however. For the 'live' videos, I get a message: 'Your browser can't play this video, learn more' And when I click learn more, it says my browser is up to date. I tried streaming other videos from websites like crunchyroll.com and none work. I followed some suggestions to clear cache, turn on video/audio settings, etc. but nothing is working. Please assist. thanks.
