I can only get widget fields created with acf pro to ajax refresh once in WP Customizer, am i the only one? any one have had this problem and solved it? Would love some help, im sure it’s an easy thing. ACF Pro 5.1.0 and up should work well with the customizer unless i missunderstood it completely.
This is due to lack of core capability in the wp customizer. To my knowledge, the customizer currently is only built to work with theme options, theme mods (widgets and menus). Hopefully post objects will come.
