I have been unable to access my bank account as I need the mobile security app to generate my security code. The updated version requires iOS 13 and my iPhone 6 is only 12.5. Please can you help. I love my iPhone 6 and have no intention of buying a newer model because businesses have foolish chosen to alienate them and possible lose them (been my bank for 29 years!).
Apple Team, please can you help me.
