FNBA Mobile Banking

I’ve been using this app for a few years now. As soon as I had downloaded it, I had set up alerts for my accounts to notify me when my balance was either above or below a certain amount. And now when I went to remove the perceive ones and put new amounts, it will not allow me to at all... I type in all sorts of crazy amounts and the “save” button, will not POP up for me to click it with my finger...This is quiet frustrating because that’s the only way I’ve been able to keep track of what is taken in and out of my account.

I have used this app for years. But when I had my computer updated and removed an old email address and used my newer email address, I realized I needed to change my email address with the bank. So we did that. when I went to re-install the app it’s in the cloud. And I think the cloud has my old email stored so now it won’t open the app at all. What can I do?
