                                },

                            application_context:{

                payOrder(orderData);
            });
        },

    function payOrder(paypalOrder)
    {

        let ajaxData = {
            method: "POST",
            url: URL_WEB+url,
            data: {paypalData: paypalOrder, paymentMethod: ''},
            async:false,
            success: function(result){
                result = $.parseJSON(result);
                if(result.success){
                    location.href = result.success;
                }
            }

    call_files_ajax_form(allData,url){
        let results;
        let ajaxData = {
            method: "POST",
            url: URL_WEB+url,

                if(result){
                    results= JSON.parse(result);
                }
            }
        };
        $.ajax(ajaxData);
        return results;
    }

😕 Actual Behavior

The Paypal button is not displayed in those browsers. We see that in those browsers, when we check the Paypal information, it returns empty button instances, while if we check in other browsers or on the computer, it always returns instances with elements.

On Chrome browser:

On Mi browser:

🤔 Expected Behavior

The button should render and work normally in all browsers.

🌍 Environment

• Browser: Mi browser, Samsung browser

The same. Doesn't show in non-webkit mobile browsers.
