Slow, buggy and unintuitive. Diamond rewards scheme tedious. Support is useless. Security is rubbish... You can either have it so that you enter passcode *EVERY* time you visit the app or never! Ridiculous. So if you go away from the app for a split second to do a calculation or check prices, or email or 2FA, or whatever, you have to re-enter the passcode. It's so tedious. Why they can't have a timer like 30 seconds away from app and then you have to reapply the passcode I don't know🤷🏻‍♂️
