When viewing conversions in Google Analytics, I'm not able to see where my customers had originated from. When people leave to pay and return to the receipt page, all that is being recorded is their landing on the /receipt page. I'm trying to track how successful my campaigns are, and it's a bit difficult to do when all the transactions show up as "direct" traffic, with the first entrance being the receipt.
I went through all the steps listed for setting up Google Analytics in Foxycart. I use Google Tag Manager instead of inserting the code in each page, but I don't think that would make a difference.
