ALMOST perfect

Much improved over previous versions. Very fast and convenient. My one piece of feedback would be to make the push approval better. Currently when you pull down the approval alert that appears on your phone, you can click the options “approve” and “decline”. When you click either of those two options, it then opens the app. Why does it need to open the app? I just want to be able to approve or decline from the alert itself without then opening the app. This is annoying, but not a deal-breaker.
