Autopilot - Can't delete devices

[Deleted]

I have been working with Autopilot for a bit and just did a test where I imported a number of existing devices (around 170). Data was collected via the Powershell script invoked remotely. I was able to delete almost all the devices, but several (5) can't be deleted. I can see them in Intune under "Windows Autopilot Devices". I cannot delete these machines no matter what I try. They do not exist in AD, nor show as managed by Intune. But, they are assigned a deployment group in the store and I can't see a way to remove them from the store deployment group.

Any ideas on how I might be able to remove these devices would be appreciated. Trying to delete all the devices so I can start over.

Thanks.

Letting it sit overnight cleared up the problem. I was able to delete the devices the next morning.

Dynamic Device groups will need at least 24 hours for cleanup.

Did you have any luck?  I have waited two weeks.
