Ok app, is not as good as other banks. Doesn't feel as secure, lots of features, but all over the place. Too many words, and not clean and clear. Much like the staff, obviously something about the culture of the entire organisation, which makes you think just what they are hiding from us, not listening just talking and talking over, and the website and app are messy, hiding behind words there too.

I'd give a higher rating but the app sometimes won't proceed into challenge questions or sending code to my mobile to authorise a payment. I can cancel but theres no reaction to touching continue. I'm going to have to physically get cash from an ATM and hand it over in person to make a payment. Not the first time this has happened, too significant a fault to rate higher.

This app just feels clunky, outdated, and painful to use compared to almost any other banking app. It feels like it was made 10 years ago and is almost enough to make me want to swap banks.
