Troubleshooting
Almost every support request is one of the four below. Work through them in order before writing to us, because the answer is usually here.
The web part is not in the toolbox
The package was uploaded but not deployed, or it was deployed without the tenant wide option and the app has not been added to this site. Open site contents on the site and check whether the app is listed. If it is not, add it from my apps.
It loads but shows nothing
This is almost always an unapproved permission request. Open the SharePoint admin centre, go to advanced, then API access, and look for a pending request naming the package.
It works for administrators and not for everybody else
That is the permission model behaving as intended. Confirm the affected user can open the source site or document on its own, and fix the access there rather than in the tool.
It stopped working after a tenant change
Check whether the permission grant was removed, whether the app catalogue was moved, and whether conditional access now blocks the Graph call for that group. All three produce the same blank result.
Collecting detail before writing to us
Open the browser console on the failing page and copy anything logged by the web part. Include the tool name, the version from the specification table, and whether it fails for everybody or only some people.
