Front end submission form not displaying CPTs

Hello,

You can still use the filter hook rwmb_frontend_dashboard_query_args to adjust the dashboard, here is an example:

add_filter( 'rwmb_frontend_dashboard_query_args', function( $args ) {
    $user_id = get_current_user_id();

    if( $user_id == 1 ) {
        $args['posts_per_page'] = 30; // show 30 posts based on user ID
    }

    $args['order'] = 'DESC';
    
    return $args;
} );
