Meta Box

Unfortunately, using the filter rwmb_frontend_redirect didn't solve the issue.

I'll wait for the fix, thank you.

I think I found a bug in both rwmb_{$field_id}_after_save_field and rwmb_{$field_type}_after_save_field actions.

The below code does not work with either action, but if I use rwmb_after_save_field instead, the my_other_field_id value updates just fine.

add_action( 'rwmb_my_field_id_after_save_field', function( $null, $field, $new_value, $old_value ) {

    if ( $new_value !== $old_value ) :

        rwmb_set_meta( MY_OPTIONS, 'my_other_field_id', date('y-m-d h:i:s'), [ 'object_type' => 'setting' ] );

    endif;
}, 99, 4 );

Oh, I already saw the answer in your new pricing page:

“To bundle Meta Box to other products, you must use the Agency license.”

You can close this, thanks.
