Agree with @mitchell-dev that there still functions/hooks that need to be added to make this feature working properly.
I decided to spend time testing this feature before applying to my theme code.
@lgladdy Please take into account this one. Many thanks.
@creativelogic This is the answer I received from the ACF support.
Hey there,
Unfortunately, this is expected behaviour. You’ll need to manually rename your local JSON files to match the new file structure if you want to apply it to an already build website.
Thanks,
Liam
So I think we can wait for the answer from @lgladdy in an upcoming release to fix this issue. Actually, I didn’t use the hook acf/json/save_file_name
and still using the old json file names because it didn’t work properly.
Thanks for the information. I’ve just submitted a request asking the developers to take a look.
