@William_MOORE, Are you talking about the new mobile app or the web interface?
Note there's nothing wrong with the hosting. Video is working for many people on many platforms. Not that this is any comfort to you since it doesn't work on your setup but just letting you know that we are constantly monitoring our servers and they're not the problem.
Also I feel that is a little strong to say the app is "useless" without video... People do many other things with the app than just watch their camera feeds. Like, start/stop prints, see which printers are online, check % complete, time remaining, browse for designs on thingiverse, etc.
