Hi, Can you try the following and let me know if this works for you. use the following Azure Sphere CLI commands:
azsphere device list-attached
This will return the attached Azure Sphere device id (a 128 character string). Then use the tenant name, and device id (the device needs to be unclaimed) to create the tenant.
azsphere tenant create --name MSW --device <your_device_id>
Please let me know the result! Mike
