WordPress Posts not Sending to YouTube Channel

Hello. We just purchased the plugin and authorized the app with YouTube having watched your training video. Our app is authorized. When we create a test post with a video, the green YouTubeOMatic submitting bar does appear briefly, but disappears after approx 25%.  The video is not uploaded to our YouTube Channel.  The post saves, and the video is embedded. We re-authorized the app several times. Please assist.
