Can't Transfer Video to YouTube

[Katherine5FE0]

I've been experiencing problems with this product for a while.  Example: YouTube is unable to process the video.  The full video is not transferred.  The full video is transferred but there's missing audio, etc.  

At this point in time, my main problem is getting a message after rending but before transfer that says it can't connect to my social accounts (or some similar wording) and I can try later.  This never works.  

I am planning to try to save the video to an external hard drive and them upload to YT through YT itself unless anyone has an idea of why this is happening.  Would appreciate any feedback.  Thanks in adance.

The problem is that YouTube keeps changing their interface.

That is exactly what I do - export e.g. to a MP4 file and then upload.
Has the advantage that you can verify that the resulting video is OK before uploading.
