Google Analytics Custom Campaigns not reporting Revenue

Question

I have created custom campaigns and completed standard ecommerce transactions with the UTM parameters set in the URL when the user hits the site initially, but my campaigns continue to say 0 revenue. My transactions are showing in Google Analytics, but they are not being attributed to the campaign. Can I have some help on the potential holes in my setup? Any insight will help.

Ecommerce Product and Revenue expected on the Campaigns

Campaigns that have no Revenue attributed to them

Answer 1

I found my issue, cache. I have done hard refreshes before every test, but I went into Chrome tools and clear EVERYTHING. Cookie, cache, everything. And Cross-Domain tracking for Custom Campaigns started working! For reference here are the scripts for the two sites:

Site 1:

ga('create','UA-xxxxxxx-x'','auto', { 'allowLinker': true });
ga('require', 'linker');
ga('linker:autoLink', ['site2.com']);
ga('require','ecommerce','ecommerce.js');
ga('send','pageview');

Site2:

ga('create', 'UA-xxxxxxx-x', 'auto', { 'name': 'client', 'allowLinker': true });
ga('client.require', 'linker');
ga('client.linker:autoLink', ['site1.com']);
ga('client.require', 'ecommerce', 'ecommerce.js');
ga('client.send', 'pageview');

Also, I added site1.com and site2.com to the Referral Exclusion List in GA and the UA key for site 1 and site 2 are the same.
