Just unbelievably awful. Not just the app, but the customer service provision too. Really regret opening a business account with this bank. App worked (in it's quaint old-fashioned way) up until Jan. Then locked out of account until I could get through to customer services. The message 'we are experiencing an unusually high volume of calls' is inaccurate - I've phoned several times and the message is always the same - so it can't be unusual - it's usual and you're not paying enough to support the shoddy systems. 3rd day phoning I manage to get through (after an average 30mins on hold each time). Go through a bunch of settings and am told it should be fine the next day. One week later still not working. Complete waste of time. Just terrible.
