Shopify Marketplace Connect

This app has been nothing but a headache. Support usually has no clue how to fix things, although they are usually very nice. It's unfortunate because this app is totally necessary if you sell on Walmart. It would be so simple to explain how to fix the app but seems there have been no upgrades on this app in forever. It's a pity. I wish someone that works at this app/company would actually fix it and make it work properly.

EDIT – After several support attempts — the main issues with the app still persist. Want a custom product detail page for shopify—that's awesome! But NOT awesome if you realize that EVERYTHING SYNCS TO WALMART AND THERE IS ZERO CUSTOMIZATION.
