My old Premiere Element 10 could not publish directly a film in Youtube.
I had to publish a file in my computer and upload it in Youtube.
Now with Element 12 I can do it. When I only had one account in Youtube, the film was published OK.
But recently I had to add a new account to publish films for a private company in a second account belonging that Cy and It works well.
The problem is that I cannot publish films back to my private account.
All publishing ends in the private company´s account.
If you have a clue of that problem please, send me a message to firstname.lastname@example.org
