This has happened to me on multiple episodes, including "Naruto Shippuden","Attack on Titan", and others. They are not specific episodes from what I can gather, but it may be my IPhone 4s. I have full internet, so that s not the problem. (Have not tried to reset the router/modem yet). When I go into the video, everything's there (The pause button, auto play, etc) for a second, then it either goes to a black screen which leads to nowhere, or to an ad which then leads to the same black screen.A quick answer would be appreciated, thank you!
