Google Analytics widget does not show original page source

We've tried this solution, but are still losing our source tracking because before it redirects to our /thank-you page the users are directed to a unique Jotform URL.

Any ideas how to fix this?

I'm not that familiar with how Google Analytics work, but I hope the following suggestions would help or at least gives you an idea. 

1. Add a google analytics tracking code using this widget. After that, can you embed your form using the full source code to exclude the Jotform Domain on page clicks where the form is embedded.

2. Try adding the "?utm_nooverride=1" to your custom thank you page.

Note, that mentioned widget is based on a Classic Google Analytics, I think it will not work with the new Google Universal Analytics.

Please let us know if this helps.

Thank you.
