I'm having trouble with YouTube, whenever I try to load a video, it just sits there with the loading circle and does nothing else. It will load when I'm on wifi but not when I'm using my data. I've tried using 4g and 3g, no luck. I've also used the app and the mobile site, neither work. I've uninstalled the app back to stock, deleted all cache and everything. I don't understand what's wrong with it. Thanks for your help.
