@Jan Hansen Thank you for reaching out to us. To start troubleshooting this issue, would like to start from
dsregcmd /status and check whether any issues about the device join state.
Prerequisites:
- Have you signed in with a hybrid user ?
- Do you have PRT on the device ? Also any AADJ errors ?
- Version of Windows 10 client ( Windows Client version is >= 20H1 (2004). )
Share the dsregcmd /status output from the device to investigate further.
