Gravity Forms Referrer Issue

[GerardDon]

I am using the Gravity Forms Marketo Plugin on a Wordpress website. When someone fills in a form on the site it is passing the details to Marketo correctly via API. 
In my smart campaign I have a fills out form trigger with a constraint of Referrer URL.
It works every time for me but when my colleague fills in the form the referrer information is not sent. 

Anyone else have any similar issues? Or recommend a best practice for using Gravity Forms?

@GerardDon ,

If it works for you and not your colleague, that suggests something different in your set up?

Do they have a plug in that is stripping referrer information?

Cheers

This is a bit odd! Do you see a filled out form activity in the test record's activity log when your colleague submits the form? Silly questions, but are you and your colleague testing this on the same WP environment? I've seen people testing the same functionality out in different environments (with the feature/plugin installed in only one of them), and then scratching their heads out thinking why it won't work for the other person.
