What’s Fixed
If your site sends property views with the Website Pixel’s custom code (ssPixel('track', 'property_view', { ... })), any view sent before the visitor was identified was discarded. A visitor who browsed several listings and then filled in a form became a contact whose activity began at the moment they signed up.
The pixel now holds those earlier views on the visitor’s session. When the visitor is identified, the views are added to the new contact’s Activity timeline, property view counts and Smart Lists, each at the time it actually happened. A view the pixel also detected on its own is recorded once, with the extra detail from your code.
Property view automations treat these views the same way as other views recorded at identify time: a view from the last day can trigger them, an older one does not.
Property views and saves fired on the very first page load, before the pixel had a session, are now also queued and sent as soon as the session exists, instead of dropped.
No change is needed on your site. The tracker version on the page moves from 1.5.5 to 1.5.6.
Views that were discarded before this fix can’t be recovered, because they were never stored.
