How can I list AdType items?

Summary

The AdType ListingType is no longer used to list items. This specifically impacts Real Estate categories where the AdType listing format was popular.
The new way to list these items is to use the LeadGeneration ListingType, and the ClassifiedAd ListingSubtype.
Here is an example of the old way and the new way to list items that are traditionally known as Ad format (the ItemSpecifics details have been left out for readability):
