I've just started using UA on my new shopify website. Last night I sold a number of products, but Google Analytics is misreporting which half of them are. So e.g. I sold A, B, C & D and Google Analytics tells me I sold A, B F & G.
What might be the problem?
Thank you in advance.
Have you tried checking how the ecommerce data is being sent to GA? For example, if you are sending the data after the DOM has loaded? Can users click away from the confirmation page before the GA code fires? Check the positioning of the code.
