So, on that old Eken tablet, the Youtube app started acting up. I am treated with the "An error occurred" when attempting to sign in with the app. If I try to play any video, I get the "Unsupported video format" error which doesn't make sense at all.
So, I started looking into a possible fix for it when I found this helpful link. Turns out, it is the answer! I used the Youtube 4.1.23 apk off the web and it works like a charm.
