It's not going to the next page.

This behavior is typically caused by the browser blocking cookies or other site data that the billing page needs to finish loading.

Try these steps in order:

1. Allow cookies and third‑party cookies
   • In the browser settings, make sure cookies are allowed and that third‑party cookies aren’t blocked.
   • If there’s any tracking‑protection or anti‑tracking extension, temporarily disable it for the Microsoft billing/Azure site.
2. Enable pop‑ups for the site
   • If the browser shows a “pop‑up blocked” icon in the address bar, allow pop‑ups for the Microsoft billing/Azure domain and reload the page.
3. Clear cache and cookies for the site
   • Clear browsing data (at least cookies and cached images/files) and then sign in again to the Microsoft 365/Azure portal and retry the billing profile step.
4. Use an InPrivate/Incognito window
   • Open a new InPrivate/Incognito window and repeat the billing profile/credit usage flow there. This bypasses cached data and many extensions and often lets the page load correctly.
5. Try another browser or device
   • If it still hangs on “loading”, try a different browser (for example, Edge instead of Chrome) or another device to complete the billing profile.

If none of these steps work, contact Microsoft support from another browser/session and provide a screenshot plus the time and region; support can check for a backend issue with the billing experience.
