I noticed that the Activity ID is visible for some activities, but not
others, in the Activity Overview screen.What steps are required before
the Activity ID displays on that screen? Do I need to take the activity
to a certain point in the process?
The "Create a Multivariate Test" documentation and the Adobe Target UI
suggest that Visual Experience Composer is required to run Multivariate
Tests. Is this true? Can I instead setup and run a MVT with JSON Offers
or anything other than VEC?
