Why does Messages app keep crashing?
I have a lot of messages in the messages app and I've been trying to delete all of the old ones for some time. Every time I attempt to delete them, the messages app crashes and returns to the home screen. When I click back to enter the app again, the "New Message" window appears, none of my recent messages are there, and when I go to Settings > Messages, iMessage is turned off. Does anyone know why does this happen or how to prevent this of happening?
