Any changes made to a Dynamic Product Feed (manual or automated) are referenced on a live experience almost immediately (add, edit, removing products).
This works well for automated feeds relying on product availability.
But it does not work well in some situations where users want to modify some of the fields in the feed and adjust the mapping and logic accordingly because any updates in the feed will be referenced before they can update the mapping and logic, QA, and republish the mapping and logic.
The way to work around this more often than not is to create a copy of the experience and a copy of the feed, and then to QA on the copy until the changes are confirmed as working. Then you can go back to the live quiz and make those edits quickly.
