When on a gutenberg edit page, the acf unload hook is disabled, meaning that if there are modified acf meta fields on a post (but no changes to the post itself), navigating away from the page loses those changes without a warning prompt
the code is intentionally disabled (see gutenScreen.initialize
in acf-input.js), but I’m not clear why this is done, nor how best to re-enable it to get the prompt back. Does anyone have a recommendation?
