I tried it on september 10th (as i see the date of the first message i sent him asking for the information of when the slot would be available) , i tried it 5 minutes ago , and it is the same.
Just curious...when did you try this? I had this happen to me once when psn was down for maintenance and I didn't know. I tried the next day and it worked.
But why if it is "shareable to 2 consoles" there appear 3 consoles activated in the qriocity? Maybe something happened as you mentioned related to the maintenance... i thought about asking him to create a user in his console, connect it to the account and then try to deactivate it again from the XMB.
