The event submission page issue is most likely related to the browser session or cached data.
Try the following steps in order:
- Use a supported, up-to-date browser such as Microsoft Edge, Google Chrome, Safari, or Mozilla Firefox.
- Reload the page with a hard refresh:
- Windows: Shift + F5
- macOS: Command + R
- Copy the submission page URL and paste it into a new browser window or tab.
- Clear the browser cache and cookies, then try again.
- If using Chrome and the page appears stuck while loading, ensure cookies and pop‑ups are allowed for that site, and try Incognito mode.
If the page still does not load correctly after these steps, report the problem through the relevant Microsoft Learn or event support channel so it can be checked server-side.
