this is not working anymore. how to disable mandatory fields on checkout?

i tried several things its not working

/**

• PMPro: Entfernt Pflichtfeld-Fehler für State und Phone im Checkout

• Greift nach der internen Validierung
  */
  add_action( 'pmpro_checkout_preheader', function() {
  global $pmpro_msg, $pmpro_msgt;

  if ( empty( $pmpro_msg ) ) {
  return;
  }

  // Messages können String oder Array sein
  if ( is_array( $pmpro_msg ) ) {
  foreach ( $pmpro_msg as $key => $msg ) {
  if (
  stripos( $msg, 'state' ) !== false ||
  stripos( $msg, 'phone' ) !== false
  ) {
  unset( $pmpro_msg[ $key ] );
  }
  }

   // Wenn keine Fehler mehr da sind → Status zurücksetzen
   if ( empty( $pmpro_msg ) ) {
   	$pmpro_msgt = false;
   }
  

  } else {
  // Fallback bei String
  if (
  stripos( $pmpro_msg, 'state' ) !== false ||
  stripos( $pmpro_msg, 'phone' ) !== false
  ) {
  $pmpro_msg = false;
  $pmpro_msgt = false;
  }
  }
  });

@cremigerhonig This is still a valid hook and available in core. There may be another plugin requiring the fields running after this one.
