Hi guys. My dad has installed Mojave on his iMac. Since then he has been unable to play live streaming in a website on any browser (Safari, Chrome or Firefox). He can use Netflix, Youtube etc just nothing LIVE. When he presses the play button nothing happens. I have cleared caches and browsing history, reinstalled Flash. There is obviously a glitch somewhere but I don't know where to look. I am still using High Sierra and can watch these videos he is having trouble with. Hoping you can help.
