Having the same problem as others with the app not being able to connect to my bank account, i quickly realised it was because QB only seems to authorsise through banks online personal banking using banks URL but as i had bank app installed it kept diverting to the bank app where it could not be authorised. I then used my tablet instead to connect account and without the banking app interrupting their authorisation method it worked, their way of connecting bank accounts is very outdated!
