Scenario: 1. In the iOS Aeroflot app, log in to an Aeroflot Bonus account and enable Touch ID. 2. Change a password for the Aeroflot Bonus account using the web site. 3. Try to log in to the Aeroflot Bonus account using the iOS app. Problem: The iOS app always asks for Touch ID and says that login/password is incorrect; at the same time there is no way to enter new credentials, even if use a wrong finger and select "Enter username and password" in the Touch ID alert. Seems the only way to fix this is to re-install the app.
