Hi, I am trying to withdraw tokens from the Bitshares system. I have tried BTS to Poloniex, open.BTC to BTC address, but when I click the Send button nothing happens. Same problem in the BTS wallet and on OpenLedger. What am I missing? Some kind of permission or setting? I am new to Bitshares, could someone please help?
