Hi everyone. I wonder if anyone can help me. My partner has just bought a new iPhone 7 with iOS11. The Contacts app is nowhere to be seen! All her contacts are on the phone and are available via the Phone app, messages app etc. I thought it would be an easy fix by going to the App store and downloading it. But in the app store it just has an Open button rather than a Download one which points to it actually being installed on the phone. The app can be opened by Siri also. Anyway, if anyone has any suggestions, it would be greatly appreciated.
