I was just about to ask the same thing. According to v5 features:
The .json files can also be used on other websites even if the field group does not exist in the database. This allows you to create fields on your local website, commit the updated or new .json files and push them to your live website.
I’ve just set up my project on staging and after activating ACF and the theme with JSON configs, I’d expect fields to auto-apply but they didn’t.
Is there a bug or am I misunderstanding this feature?
