Sorry for the late reply voidsoul. Yes I managed to power down as you explained and now I can see my Steem. All I want is to send them in a platform I can sell them. How to proceed, choose "Transfer", "Market", "Trade" ? I'm not used to this platform, find it cumbersome and complicated.
I tried to reward your help, no success.
I try to move my STEEM, can't find out.
I manage 68 different coins on 19 different platforms and wallets. Steemit is definitively not for me unfortunately
so I try to escape but you are the only one that seems able to help.
Many thanks for the help so far, dealing with unsupported platforms gives me Kafkaian anxiety.
And yes I remember all my passwords and keys.
