I've got the opposite problem of a system not going to sleep: my desktop pc is going to sleep while I'm using it. Playing a game, watching Netflix, browsing the web and suddenly the system goes into hibernation.
The eventlog says the cause is the battery. I do have a UPS battery connected but I'm pretty sure the system was not running from the battery. I've never had this problem with Windows 7 and 8 but since I upgraded to Windows 10 this hibernation event occurs a couple times a week.
However, I did notice something. The app is full screen, when I drag it to the left of my screen so it resizes to a small vertical band the videos do show up. I can resize the window by dragging the resizebar to full screen and keep seeing the videos. But when I click the back arrow (back to shows) then click Azure Friday again I'm still back to a white screen.
This only seems to happen with Azure Friday. Ping, Level Up, TWC9, the 'Home' screen, no problem.
