Hi @samppp,


first of all I want to give you an advice and go for azure ad joined device. There are very minimum reason to enroll your device as a hybrid. On premises services can be used if you setup ad connect correctly and the root certificate is installed on your device.


but back to your problem.


Did you het welcome to your organization screen during enrollment or welcome to Microsoft? if yes, it looks like you don’t have an autopilot profile assigned


if you get the welcome to your organization screen and you logon with your corp credentials and after the enrollment your device is azure ad joined, you have to check your autopilot profile because I think it is configured to azure ad joined instead of hybrid ad joined 


please let me know if this helps you to find why your device is azure ad joined after enrollment.


kind regards
