They don’t seem to have much of a relationship with whomever devleoped the plug-in. My store broke and won’t let me add new products or variants to existing products after the May 27 update. I was on vacation and came back to this mess.
I’m about to create a subdomain [subdomain.maindomain.com] and see if I can create a whole new store with the current versions of WordPress, Woo and Prinful.
