HOW DO I UPDATE THE COUTTS APP ON AN APPLE DEVICE?

Apple upgrade their operating system (iOS) regularly. Keeping your software up to date is one of the most important things you can do to maintain your Apple product's security. We highly recommend that you keep iOS and all apps on your device up to date at all times. To make this as easy as possible, we recommend that you activate the automatic update features on your Apple device (both automatic software updates and automatic App updates).

To maintain access to your Coutts account(s) you need to make sure you always have the latest version of the Coutts app. If you have turned off automatic App updates, refer to Apple's How to update apps manually on your Apple device guide.
