iPhone SE messages are not loading
My wife just got the iPhone SE and selected to load all her previous messages from her Samsung. Now on personal conversations all messages are gone and it shows a loading icon, and any new messages disappear within seconds. We tried resetting, turning off iMessage and turning the phone off, signing out, etc and nothing is working. Please let us know how to fix this
