Changing Product Collection in Mobile App

I’ve got two custom collections set up in my web store, retail and wholesale. They contain products priced at Retail pricing and wholesale pricing. Have two stores on site, one that uses retail collection and one that uses wholesale collection and that all works fine. User must be signed in to see wholesale collection. Problem is when using Wix Mobile App and they get to member area to shop, it defaults to All Products collection and despite looking through all help articles and numerous web searches, I cannot find a way to change this to one of the two collections. Anyone seen this problem and know how to correct?
