Seems to be the same as described here: https://support.advancedcustomfields.com/forums/topic/use-parent-key-to-get-the-parent-field-object/
So, once using the ACF PHP functions to get a field object, via for example get_field_object(), the returned array holds the post ID of the parent field under the ['parent'] key.
While on another WordPress installation, under the exact same function returns the ACF key of the parent instead of the post ID.
How do I make sure, that I always receive the key value and not the ID value?
