iMessages are missing on new iPod
I recently got a new iPod (mine had been stolen).
I logged in and opened the iMessage app, and my recent conversations are missing (the newest available one is from March 23).
Is there a way to get those messages back, or should I just ask whoever sent them to send them again?
It is an iPod touch 5, and is running on iOS 8.3.
