Referrals from US site showing in my UK data
I have a .com site and a .co.uk site. They are both on the same server. They are both using different Google tag manager scripts.
My .uk analytics are showing referrals from my .com site. Firstly, it shows multiple landing pages (including marketing landing pages), yet to come to the .uk site from the .com site, it always takes you to the home page. Also, the referral paths are showing from multiple pages which contain no links whatsoever to the .uk site. Lastly, the visits have transactions associated with them.which just wouldn't happen as my sites are explicitly location based.
It happens on all browsers, all devices and users are not all in the same location.
Any help would be greatly appreciated.
