Thank you for such an informative post.

Thanks again @Brian_Johnson_. I'm managing two different domains. The QSP Data element works for domain1, and your guidance helped me get to the right place. Domain2 adds a subdomain once the user goes into the commerce section of the site. There must be something disrupting the users session when moving over to commerce. Even extending the duration to visitor did not work unfortunately.

Thanks @Brian_Johnson_. Would it be the same session if the user is redirected to alternative payment type domain, such as paypal, in the same tab?
