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.
If user clicks on our ad and QSP ?ex_id=123456 is appended to the URL of
our landing page, is Launch able to store that QSP? I want to later
retrieve that same QSP value from the landing page at the point of
purchase, in the same browsing session, and insert that value in a
parameter of a marketing tag.
