Hi there @MyPistachio!
Don here from Shopify.
Can you confirm for us here if you are referring to the Stock Sync app from our app store, or something else?
If so, you can contact them directly with any queries you might have about their product by using the contact details listed there on the app store page or by clicking on 'Get support' next to the name of that app in the Apps menu in your Shopify admin.
If this is not what you're referring to here, just let us know and provide as much info and detail as you can on the issue so we can check it out with you.
