Have any of you who upload videos to YouTube lately noticed that, it's taking a significant longer time for videos to get processed. Earlier used to be within 5 - 10 mins but now it can take 30-45 mins even for 1080p videos @TeamYouTube
Just dont make the video live immediately. Make sure its viewable in full resolution before making it live. Its annoying to see video live and in 360P for long time. I have missed few videos due to this as I never got back to resuming those videos later.
