I cannot deauthorized computer and I have already contacted support.
I followed the instruction but it did not work.
Support told me to wait for reply but I think around 2 weeks is to long for reply.

I guess that I subscription IOS only so I cannot deauthorized my window machine. Do I understand,right?

Hope Corona's stuff are keeping in touch in my case.
Thanks.
