Messages not showing contact name on lock screen
when my iPhone 6 is locked some messages show on lock screen with contact name, but others just show the phone number. To know who these are from I need to open the message app. The name of the contact is then shown. Spoke to apple support and fixed issue by deleting the contact and also the entire thread from that contact. Works but means I now don't have the thread. This happens to random contacts, some are iPhone users, some aren't. There is no set pattern. Anybody else having this issue? And anybody know of an alternative fix? First happened after iOS 9, since updated to 9.0.1 and most recently 9.0.2
iPhone 6, iOS 9.0.2
