Message Failed To Send notification when turning on iPhone
Every time I turn my phone on I get a notification for a message that failed to send over a year ago. The notification is not always for the same person or message, but I don't get all variations of the notification each time I restart, just one of three. A quick Google search has shown numerous people with this problem, but no solution that works for everyone. So far I've tried to solve the problem with these actions, but none have worked:
- Find the old messages that failed to send (I couldn't find them)
- Edit > Read All in Messages App
- DFU Restore
