Unable to withdraw more than what I've deposited. Over the years my investment has grown a decent bit, however, recently I've wanted to take some money out to fill up my lifetime ISA before the end of the tax year. I sold some stocks and tried to withdraw but discovered I can't withdraw above what I've invested? Asked the AI bot and it confirmed this. Is this true for anyone else? If this is true this seems really concerning which I have already taken some months trading already
