Fingerprint login Android & other new mobile features


We’ve just done a Mobile release with these new features:

Android fingerprint login (Android 6.0 and up)
Close account for YouMoney customers (Open and Closing accounts on Mobile for Total Money customers will come in a later releas).
The Watch app has been upgraded to run on Watch OS 2

The app is so much better with fingerprint login.

One question about apps getting updated, sometimes when an app updates it moves to the last in a list of apps and other times it stays in the same position. Is this something that can be controlled by the person creating the app or is this just a random android thing? Because when I updated it moved the app but in the past the icon has stayed in the same position.
