I've been having this also. YouTube is not working correctly. I know they are doing something because it was fine 2 to 3 weeks ago. Now it's buffering like crazy and if at the same moment I take out my Andriod phone which is on sprint plays within 10 to 15 seconds. I usually get 5 mbps with Sprint LTE in my area. Sprints LTE is as slow as everyones 3g. I can do speedtest.net on my computer and at that very moment get 22mbps down and 3.5 up. With that I should be able to do 1080p but its even buffering on the lowest setting which is something like 360 something. They are for sure doing something. Isn't there a throttle test we can do.
