I hope this helps to explain some of the errors you're receiving while attempting to publish to Facebook. For the digital products that you can't list through the Facebook Sales Channel, as a workaround, you can post as a regular post via Facebook, and link directly to your product page. Alternatively, use permalinks to preload the cart for customers so they can check out immediately with the advertised product.
Please feel free to reply if you have any questions.

You're so welcome. Glad you were able to find out sooner rather than later. Hopefully, Facebook will allow digital downloads in the near future!
Stange, I'm not getting a password screen when I click on the link above. Please try the native link to the youtube video featured in the post above on permalinks: https://www.youtube.com/watch?time_continue=11&v=HTgd2raL9Vo
