LDR2688 The next thing to do is to make sure that there aren't any other Windows Diagnostic data settings that are blocking telemetry that got there via Settings Catalog, Group Policy, or other channels. These are listed today in our documentation at Use Windows Update for Business reports for Windows Updates in Microsoft Intune - Microsoft Intune | Microsoft Learn, but in short check that you have the Windows Diagnostic Data setting to Required or Basic or higher, Configure Windows diagnostic data in your organization (Windows 10 and Windows 11) - Windows Privacy | Microsoft Learn , also check that "DisableOneSettingsDownload" isn't enabled. These are other settings we know about that can also block client telemetry from being sent for reporting. The defaults for these settings work fine, so it's only if somehow these were configured sometime in the past that it becomes an issue.
If it's not those, please DM me so I can get your tenant information and we can look closer into this and see if we can't troubleshoot and get your reports working for you.
