I I'm trying to setup conversion tracking but somehow it's not working. I have a bit of a complicated flow. landing page -> website (form) -> payment page (different domain) -> website (confirmation) After clicking ads, users land on a landing page with a CTA. The CTA button takes them to the form on the main website. After submitting it, they're sent to payment page that's hosted on different domain. When payment is complete, they're redirected back to the main website. I've set everything up with GTM. I can see that the tag fires on the confirmation page with Tag Assistant, but conversion aren't counted. Does those travels between the landing page, form, payment and confirmation impair the conversion tracking? Should I use something like cross domain tracking?
