Slowing way down

I would love to give this app 5 stars, as I utilize this app so frequently, however, even after this most recent update, it takes so long to move from one function to another that it often times out. Can y’all speed things up a bit, please? I’m not even doing much more than transferring funds, paying a few bills (same things I’ve been using the app for for years) and checking recent activity. The app seems to move slower and slower every time I try to use it. No bueno.

Face recognition

This app works great, but would be nice if it was compatible with face recognition though on the iPhone!

Understandable Problems but easy fix

The update has made some issues with Touch ID. For awhile I had to type in my password but uninstalling and reinstalling fixed the issue. The update has made the look of the app so much better and easier to understand. I manage almost all of my money through the app and rarely use the computer. This makes banking much easier as I can move money with the transfers super easily.
