I face this too on my Mi Box 4k, surprisingly it never happened with my Mi TV Stick though
I'm also facing the same issue on my Mi Box3
Mi box?
I have the same issue , the way I fix it is just going back 1 minute earlier to the stream .
I get something similar every once in a while watching YouTube through Chrome on my computer
I have the same issue on different boxes running Android TV OS (Mi Box, TiVo, etc.). Sometimes going back and retry works
Mi Box & Mi TVs have this problem, with YouTube live streams with vp9 codec
My Mi TV 4X Pro running Android 9 also has the same problem with YouTube live streams.
I saw this happen on my MiBox S when I tried to watch Samsung Unpacked few days ago.
It's an issue with VP9 live streams, there's nothing you can do to fix it, my suggestion is to report the issue at the YouTube Feedback website.
I would suggest getting a better box, like the Nvidia Shield. Or for something cheaper try the Mecool box. Or just get a fire stick, which doesn't have problems like that.
I have reset the app, cleared data, restarted tv, etc. nothing works. I can't uninstall it as it was bundled with the TV.
