I am trying to programatically delete an image sub field of a Group field element in ACF.
Group field name is img_gallery and the image field inside it that needs to be deleted is img2. These 2 codes is what I have tried separately but to no avail. No error is thrown, yet no effect is taking place.
delete_sub_field(array('img_gallery', 1, 'img2'), 314);
delete_field('img2', 314);
Group field -> Image Field
