[Digital Goods] PaymentRequest supportedMethods not works

[findea]

I am testing the purchase flow within the Microsoft Store–installed PWA.

I can obtain digital goods according to the following documentation, but when I initiate a purchase, the purchase dialog pops up and disappears immediately.

https://learn.microsoft.com/en-us/microsoft-edge/progressive-web-apps/how-to/digital-goods-api#purchasing-an-item-paymentrequest-constructor-and-show-method

const request = new PaymentRequest([

	  {

			supportedMethods:"https://store.microsoft.com/billing",

            data: { sku: "lse12" }

	  }

	]);

	request.canMakePayment().then(result => {

	  if (result) {

	    console.log("This browser supports the specified payment method.")

	  } else {

	    console.log("This browser does NOT support the specified payment method.")

	  }

	}).catch(err => {

	   console.error("canMakePayment Error", err);

	});

	request.show()

	  .then(response => {

	    console.log("Success", response);

	    response.complete("success");

	  })

	  .catch(err => {

	    console.error("Pay Error", err);

	  });

This browser supports the specified payment method.

The console shows the following error.

Cross-site redirect from "https://store.microsoft.com/billing" to "https://www.microsoftstore.com/" not allowed for payment manifests.

Pay Error AbortError: User closed the payment app.

curl -I https://store.microsoft.com/billing
  HTTP/1.1 301 Moved Permanently
  Date: Tue, 10 Feb 2026 09:52:20 GMT
  Server: Kestrel
  Location: https://www.microsoftstore.com/
  Strict-Transport-Security: max-age=31536000

I also tested the alternative URL : https://www.microsoftstore.com/billing. Unfortunately, it also returns a 301 redirect (to https://www.microsoft.com/store/b/home), so it does not work either.

I am concerned about why the official payment URL (https://store.microsoft.com/billing) is returning a 301 redirect. Is this a known bug, or is there a specific configuration required in Partner Center to avoid this issue?

This problem is currently blocking users from making purchases, which is causing significant disruption.

Looking forward to your help.
