Before
Earlier, you couldn't show a rule-based campaign when an intent-based campaign was shown to a user within a session.
Now
Now, you can configure a rule-based campaign also to show even if an intent-based campaign was shown in the same session.
Remember
, if both the campaigns are set to trigger on the same event, the intent-based campaign always gets the priority.
Use case-
You may want to show a low-stock campaign for a particular product along with a live low-intent campaign.
