Optimus_Robertus, Oct 22, 2017 : Hi all, I have a problem with the YouTube app; All of the sudden, it stopped working, if I am connected to a WiFi network. The app keeps on loading forever. When I am on a 3/4g network, I don't have this problem. I can also still play videos on YouTube in my browser. Does anyone know how to fix it? (I'd prefer not to reset my device....) Thanks!
