I am from indonesia , my account is "Enable" but i can't "Enhanced Accounts". I get this message "There was an error processing your documents" can't re-upload my document, didn't found button "upload here" . I dont know why bittrex doing this, if your account is still Enable, i suggestion to you to try withdraw or move your balance just for secure your fund in the meantime if someday there is a serious problem

Edit: Just for meantime if someday there is a serious problem
