Knotted Road Press review for Bookvault

Bookvault USED to work great. No longer does. If you create paperbacks as variants of ebooks, the app will not let you connect the paperback to the Bookvault store. It used to allow this. I have over 200 books where this procedure worked correctly. I've been in contact with Bookvault about this and NONE of their work arounds helped. I'm going to have to switch to Lulu in order to sell my paperback books from my store.
