Recently, that is to say, just yesterday, Youtube app stopped working on my LG Optimus Dynamic. Previously it worked fine, but as of right now - When I try to play a Youtube video, there is no -video-. Plenty of sound, just no actual video. I have searched online for a solution but only seemed to find one from two or three years ago related to the Twitter official app (which I do not use). Strangely, yesterday while I was in the car, Youtube worked just fine and when I got home it didn't.
