I recently updated my iphone SE and now it seems to be keeping a count of all my sent and received imessages and texts... It won't let me mark anything as "read", but I can delete conversations for a short time, but they then reappear if that contact texts me or if I try to restart my phone. If I delete conversations, the red number on the message app doesn't change even though there is no messages present. I even tried Siri and she can't help. I've tried resetting, I've tried signing out and in again with my apple ID in the message settings. Nothing is working...HELP.
