Question: This returns a CSV and this has a field called User Principal Name, Display Name. These fields are not returning the corect value. I have been using this for some time and now on the 29 of August I started getting non valid values such as this:

'User Principal Name': 'RDRT4382ED1753CBD3D8D5C2E4FEHTFR',
'Display Name': 'ZZZZ292D9B62ACE2BABCD2FD5DCADTRG'

    It seems like this is related to a change from Microsoft to anonymize user data.

    Check this page for instructions on how to enable the correct values in reports: https://techcommunity.microsoft.com/t5/microsoft-365-blog/privacy-changes-to-microsoft-365-usage-analytics/ba-p/2694137
