Love this app

Love this app it has been such a great convenience during covid-19. Easy check deposits and loan payments. While I always avoided online banking, I find this app really great, convenient and secure. When I have on occasion got locked out customer service is excellent at fixing it immediately for me. Highly recommend!

Refuse to update iphone always crashes

I’ve been using this online app to pay my bills for over a year and it was awesome. I currently refuse to do another update on my iPhone because the last two updates have caused crashes of one program or another. The app will no longer work on my phone and won’t download the last compatible version so I can no longer use it. If you don’t have the most current up to date phone (mine is an IPhone X) with every update the app won’t let you do any banking or transfers or pay bills. I’m switching banks soon just to pay bills online- it stinks and is a hassle that I can’t use the app without updates to my year old phone.

When it stinks, it really stinks

While this app is pretty convenient when it works, the issue is, it never seems to work. It’s frequently not recognizing or verifying your log in info. Locking you out from seeing your account(s). Then you need to call and deal with all that. Who has time?? And don’t get me started on their website UX.
