Infinity scroll changes the asset page and it only works with articles, collections, videos, and YouTube assets. It will show all of the original asset, but then it will also show a summary card version of other assets from the same section or block. Story Summaries will remove the right rail, but using Story Summaries with Side Rail or Story Summaries with Sticky Side Rail will add content on the Right Rail including the ability to add an Ad Block there.


NOTE: Infinity Scroll uses Block ID's to organize content for sites that have Content Discovery set up.
