Virb 5.1.2 repeatedly fails to upload to YouTube

Repeatedly, I am able to upload to YouTube after exporting the .mp4 file to iMovie but not directly from VIRB Edit for Mac. Also, all of my transitions in the video are completely hosed. Don't work and cause video pauses without the transitions. Had two songs imported to the video that had the same names but by different Groups. The Edit merely repeated one of the song and omitted the really different song. It appeared correct in the edit in that the titles were listed with different song lengths but the replay of the video told a different story. The Garmin Edit for Mac is really rough! Has room for many improvements if it is to support the VIRB Cameras. Not happy with the current offering.
