Not backward compatible
I have an iPhone 6 so this app works OK for checking my balance and transactions. However, my iPad is 3rd generation so I cannot upgrade it to iOS10, but this apps upgrade instructions state NOT to upgrade to the latest version unless iOS10 has been installed. As a result, I have this one app that I have to be careful not to upgrade. Come on DISCOVER, make your app compatible with older iOS versions like ALL the other apps I have; they have not abandoned users with older devices yet, so neither should you.
