Hello @tage danielsson
Are you sure that you are using the right account to create a new Azure Sphere tenant using the attached device?
I hope you have already visited this page:
When you create a tenant, the Azure Sphere Security Service records the device ID of the attached device. Each device ID can be used to create only one Azure Sphere tenant.
You can use the --force-additional parameter to force a new Azure Sphere tenant to be created. Use this command only if you are certain that you want to use the current account to create a new Azure Sphere tenant using the attached device. A device that has previously been used to create an Azure Sphere tenant cannot be used to create a new tenant.
Normally "azsphere tenant create" should read the locally attached device ID and send it automatically. Anyone needing to create a tenant should get the device ID with "azsphere device show-attached"
and then use "azsphere tenant create -d <deviceid>"
Please try this command and do let us know!
