I have a few devices connected to my Ubuntu One account. From https://one.ubuntu.com/account/, I removed the device I no longer wanted connected. It seemed to remove successfully.
However, as a test, when I deleted some files from the Ubuntu One directory from the removed device, I noticed that the file also get removed from the Ubuntu One online account and also from all the other connected devices.
So my question is. How do I remove a device from ubuntu one?
