Hi @robertrhu
I think it should be something like this:
if( function_exists('acf_add_options_page') ) {
if( get_current_blog_id() == 1 ) {
// register the options page for root here
acf_add_options_page();
} else {
// register the options page for other sites
acf_add_options_page();
}
}
Hope this helps 🙂
