Ask the person you got the device from to log in on their account and remove your device from their registered devices. Then log in again
I've got this 2nd hand device nd I'm getting a 'Video Authorisation Error: this device is currently registered to another user...' I did login with my mail address but now this error doesn't show which devise is account/devise my Xiaomi MiBox3. And how do I get my devise's ID.
