This app is a disaster. At first sight everything looks good and with the "normal" cookies everything works fine. But how it works with the Facebook pixel is a disaster.
First we were very kindly helped by the support with a code hack for publishing the pixel on the checkout process.
Since our Facebook Ads had worked worse and worse, we went on a search.
This app or even the hack delivered completely wrong data to the Facebook pixel. In the end he counted every purchase three times.
We have been waiting for a reply from beeclever for days now. Hands off, if you use the Facebook pixel.
We are sorry to here this in your case. We have over 2k customers using fbp through our app with no issues. Our free support is limited in case of fully customized Themes and custom coding or apps not following the conventions of shopify. We love to help you, getting the app implemented correctly or contact a shopify expert helping you in this case.
