A device can only be added to one account on Proficloud.io.
- Delete the device in the account where you no longer need the device, this will delete the record in Proficloud
- Delete the Device Token on the device itself
Note: You can only add the device to another Proficloud account if the device no longer exists in any account and the Device Token has been reset. Also check the status of the Device Token on your device. In older firmware version it needs to be deleted by hand
