Running iOS 12.1 on iPhone 6S and have messages from people in my contact list show up in Unknown Senders. These are people who text often and it happens randomly with 4 contacts and 3 groups. To “fix” it when it happens I have to restart the iPhone. It’s been going on for months and have done all iOS updates except 12.2. Any ideas on how to fix permanently?

    Are these users in your contacts, or just previous people you've messaged – Ezekiel Elin Apr 3 '19 at 15:11
  • They are set up as contacts. – NancyMc Apr 3 '19 at 16:03
  • Any reason not to update to 12.2? – IconDaemon Apr 3 '19 at 17:21
  • No. Just usually wait a week or 2 after a new release. – NancyMc Apr 3 '19 at 18:17
