InAppBrowser "loadstart" event trigger issue

Hi folks,

Below code is used to open InAppBrowser and on loadstart event, url change is detected and some functionality is performed. It suddenly stopped working, any directions?

const browser = this.iab.create(orderResult.links.paymentUrl, "_self", { location: 'no' });

browser.on('loadstart').subscribe(
            (payment_result) => {
              if (payment_result.url.startsWith(ServiceConfig.baseUrl)) {
                console.log('order id: ', orderResult.orderId);
                this.utilityService.openPage(OrderDetail, { id: orderResult.orderId });
                browser.close();
              }
            }, (error) => {
              console.log(error);
            }
          );

am facing the same issue…any solutions for this?
