Download impossible despite IRM

Iron Contributor

Hi there,

I have activated M365 E5 Compliance and Enterprise Mobility & Security E5 IRM via Powershell and in SharePoint AdminCenter in my test client with the license. I then turned on IRM in the appropriate library:

Thanks a lot in advance and kind regards,
