I am hoping im not the only one who is suffering with this problem, but i have had regular problems watching videos on the RT app on the Xbox.
Quite regularly when watching the videos it pauses half way through similar to buffering. The main problem is that the video never carries on which means i have to back out and then fast forward to where i was. This is also a problem as the same can happen even when fast forwarding through the video.
My biggest pet peeve with the app is that it does not have a continue watching function, hopefully im not the only one who wants this function and fingers crossed it is a option in the future.
