I have joined this beta and have a configuration question.
The page Associate external website pages with a campaign (BETA) (hubspot.com) says “To edit the URL for the external website page, hover over the page and click Edit. In the right panel, update the website URL, then click Edit. Any updates made to the URL will affect all associated campaigns.”
The example shows a URL pointing to a subdomain.
I have since implemented and also pointed to a subdomain - but I see no records in Campaign Performance.
My question is this: can I use a subdomain as an asset or should I add each URLs to the list?
