Upgrade to Windows 11 not working on Autopilot Devices

Hi,

we are using Endpoint Manager to administer our devices. At the moment I am testing Windows 11 deployment via feature updates and it works kind of fine with our hybrid joined non autopilot devices..

When I add an autopilot azure joined device to the group for the feature update, it is not updating to Windows 11. 

If I look up in the reports tab, there stands "Offering" for the update state.. also for the devices that have successfully installed Windows 11...

Is there anything else i need to do, besides the Feature Update setting, to make the windows upgrade work on autopilot/Azure joined devices? (Or to get more/correct information out of the report tab?)

Is there something specific to autopilot/Azure joined devices that can prevent the upgrade? 

I really hope for your support here..
