Shipping In Style review for Shopify Collective: Supplier

I was using this for a while, set up everything was great. Randomly, without any changes to my store, I was deemed ineligible. Shopify support doesn't know why I am ineligible, because I have met all the steps to be eligible. Therefore, this is a malfunctioning (half working) app that the developers apparently do not care to fix as I have reached out 4 times already and just did again today!
