Dynamic content after form submission
In the dynamic content tab, changing the ALL to ANY will change how the code is setup so it would depend on the type of logic you would like to use!
Using ALL will apply an AND statement which would require all of the selections to be selected, where as ANY would require one or more to be selected.
Dynamic content directly after a submission may not always render right away as it takes some time for the information to go to the correct database in the backend, so it is usually best to have a page in between the page you would like to have dynamic content on (or if you have a developer, have them make a delay between page redirects). This applies to both landing pages and external pages with dynamic content.
