I have the same issue on scanning but strange thing is that after scanning the product the price is different from the Admin/Product.
When manually entering the UPCs, it shows the correct price. Is there a cache that I can do to clear this on my iPhone?
Bump... Same problem, here in September of 2021. We're trying to open a store today and this came up. I'm kind of shocked that Shopify hasn't responded and offered a solution. Honestly, about to go in to panic mode.
