If you are having trouble viewing a document’s version history in SharePoint, there are a few steps you can take to troubleshoot:

1. Make sure you have access to the document and the sharing setting is set to allow anyone with the link access.
2. Check the document library settings to ensure document versioning is turned on.
3. Check the view settings to make sure version history is selected.
4. Check your internet connection to make sure you’re able to connect to the SharePoint site.
5. If the problem persists, contact your system administrator and/or the SharePoint support team.
