I've set up an basic Activity with "All visitors" targeted. Within the Activity the only modification I made was executing a javascript console log.
When I open the QA link I see the console log being made. Only when I navigate to another page the console log is no longer made.
When I return to the original page the console log is made again. So the preview persists throughout my session. But it only fires on the initial page I configured when creating the Activity.
With "All visitors" targeted, should'nt the Activity fire on all pages?
