The Microsoft Copilot Studio page simply won't load

Try the following steps that have helped resolve similar “page stuck loading” issues:

1. Allow cookies for Copilot Studio
   • In the browser settings, make sure cookies are allowed (not blocked by default).
   • If using stricter settings, explicitly allow cookies for the Copilot Studio site.
2. Enable pop‑ups for the site
   • Check the address bar for a pop‑up blocked icon and allow pop‑ups for the Copilot Studio domain.
3. Clear cache and cookies
   • In the browser menu, go to More tools → Clear browsing data.
   • Clear cookies and cached images/files (at least for the Copilot Studio domain, or for a short time range like “Last 24 hours”).
4. Try an InPrivate/Incognito window
   • Open a private/incognito window and sign in to Copilot Studio again.
   • This bypasses existing cache, cookies, and most extensions.
5. Check third‑party cookie settings and extensions
   • Ensure third‑party cookies aren’t blocked in a way that breaks sign‑in or session storage.
   • Temporarily disable ad‑blockers or privacy extensions that might interfere with authentication or scripts.
6. Verify basic access and support
   • Confirm that the account has access to Copilot Studio as described in the access and prerequisites documentation.
   • If the page still won’t load after these steps, use the Copilot Studio community or open a support request through the Power Platform admin center so Microsoft Support can check for a backend or tenant‑specific issue.
