Same thing with white screen. I've noticed with everyone's comments it seems to have been since the update. Who fixes this problem? Go into bank and they are not useful at all.

For the past 2-3 weeks, I can't get past clicking "log in", then it's a white screen and nothing happens. I haven't been able to use the app at all.
