Allow user to edit - edits the whole app OR only theirs?

on components - edit - allow users to edit:
I am trying to create something where it shows examples and then they can add their own example (playbook) to it. However, if I allow them to edit certain sections or all sections, does it edit the main app or only their specific copy of it?

Depends on the setup. If the screen that their editing is already filtered to their information, then they’ll only be able to edit their info. Set a filter on the edit screen where user is signed in user.

You can also conditionally show the edit button by signed in user, so only their own examples are editable by them.
