Hi @staypuftman
You need to pass the post ID where you want to get the data form to the second parameter of get_field() or the_field() function like this:
get_field('subtitle', 99);
Where “99” is the post ID where you want to get the data from.
This page should give you more idea about it: https://www.advancedcustomfields.com/resources/get_field/.
I hope this helps 🙂
