I’ve got the exact same issue here.
I have a update_sub_field inside a foreach after which I do a get_field of the repeater right after the update, but it still has the old values even though the update_sub_field did indeed update everything correctly.
Not sure why ACF get_field is still getting old values. Thanks for any help!
E.g.
$lists = get_field('lists', $post->ID); // repeater field
foreach ($lists as $key => $list) {
update_sub_field(array('lists', $key, 'field'), 0, $post->ID); // switch from '1' to '0'
}
$lists = get_field('lists', $post->ID);
var_dump($lists);
// outputs old values
