Not ready for "Prime Time" video simply does not work

Finally found the answer here that video uploads to Captivate Prime directly out of Captivate 9 simply do not work. After messing with many video formats, various import methods to C9, i.e. using the media button, importing directly into library and importing directly into the slide, I feel that video capability is simply not possible yet. The bug is being fixed according to an Adobe rep post. Our company did a walkthrough of Prime with an Adobe rep and I asked him why video wasn't working. He said it was my firewall or browser interfering with the process and that he would find the answer. I found out here that it is a bug.  Is it possible to upload in another way? I can publish to devices, but that outputs a folder with many sub-folders and many files. Is it possible to upload those files one by one, because uploading a folder is impossible? Also noticed on one of Adobe's own demos that the video was streaming from YouTube. Am I better off creating a video library in YouTube, Vimeo or Aframe and streaming from there via links instead of having the video embedded in the C9 project?
