Hi,
Note that the Excel web app is not as fully-featured as the desktop version, so some functionality may not work as expected. If the issue persists, it may be necessary to switch to using the desktop version for this file.
For now, here are some steps you can take to try to resolve the issue:
- Clear your browser cache and cookies. This can often resolve issues with web applications not displaying properly.
- Try using a different browser to access the file, or update your current browser to the latest version.
- Ensure that your browser is allowing pop-ups and that any pop-up blockers are disabled for the Excel web app.
- If possible, try accessing the file on a different device or network to see if the issue persists.
Contact Microsoft support for further assistance if none of the above steps resolve the issue.
Best Regards.
