Hello, I just noticed (after 1 week of running ads) that fb pixel is not adding shipping charges to the purchase value, that's why Ads Manager it's showing 17% less revenue than shopify. Is there any fix for this?
Do I need to pay for yet another 3rd party app to track custom events?
Also I've had 74 sales so far, yet Fb only reports 68, that's 8% discrepancy. 6 orders gone, that can lead me to turn off winning campaigns.
I offer a coupon code for my 1 product, and also I've installed a quantity break app, and several people buy 2 or 3 items. Not sure if any of that is causing the big discrepancy, I know some differences are normal but 8% is not.
Using Adespresso or something else would help me fix the problem? Thanks.
