'terms_agreed' dosn't work in latest release

I have two shops, one is using Perch: 3.0.3 & Shop 1.2.2, the other one is on the latest release. I the checkout flow I use in both shop is:

<?php include('../../perch/runtime.php'); ?>
<?php include('../../header.php'); ?>
<?php
        $cart = perch_shop_cart(['skip-template'=>true]);           
        if (!perch_member_logged_in()) {
            include($_SERVER['DOCUMENT_ROOT'].'/anti/sklep/zamowienie/step-1-adres.php');
            perch_shop_set_cart_property('terms_agreed', null);
        }
        else  {
             if (!perch_shop_cart_has_property('terms_agreed', true)) {
                    include($_SERVER['DOCUMENT_ROOT'].'/anti/sklep/zamowienie/step-2-dostawa.php');
             } else {
                        if (isset($_POST['platnosc-przelewem'])){
                              $return_url = '...';
                              $cancel_url = '...';
                              perch_shop_checkout('manual', [
                                'return_url' => $return_url,
                                'cancel_url' => $cancel_url,
                              ]);
                        }
                        else {
                              $return_url = '...';
                              $cancel_url = '...';
                              perch_shop_checkout('paypal-express', [
                                'return_url' => $return_url,
                                'cancel_url' => $cancel_url,
                              ]);
                        }
            }
        }
    ?>

<?php include('../../footer.php'); ?>

confrim.html file

<div class="confirm">
<perch:form id="confirm" app="perch_shop">
    <perch:input type="checkbox" value="false" id="terms" cart-property="terms_agreed" required="true" />
    <perch:label for="terms">

        Zgadzam się z <a href="../../regulamin/" target="_blank">regulaminem sklepu.</a>
    </perch:label>

    <div class="text-right">
        <perch:input type="submit" value="Zapłać" class="btn--primary btn platnosc-karta" />
        <input type="submit" class="btn--primary btn platnosc-przelewem" name="platnosc-przelewem" value="Potwierdź zamówienie">

        <perch:input type="cms" />
    </div>
</perch:form>
</div>

It works fine in the first shop Perch: 3.0.3 & Shop 1.2.2, but id does not work in the latest release. It does not redicrect to paypal or approve manual, it just stays on confirmation page.
