@TeamYouTube can you explain why MY RECENT VIDEO isn't sync with the audio? it sounds strange and yet you haven't replied to my previous tweet? https://www.youtube.com/watch?v=BTomoPWdZd8 …
hear the video and see if its sync with the audio please.
As a heads up, the duration of your audio and video track should be the same in order for it to sync. Have you followed the steps for upload issue? If not, start here: https://yt.be/help/nRFo . Let us know if that does the trick!
