Why doesn't my Ipod touch 5th generation send or receive messages from other apple device users anymore over wifi? My ipad mini still sends and received messages over wifi fine, but the ipod keeps giving me the red exclamation point with the not delivered message. I am only sending to my usual few contacts that I always send to that have apple devices. I don't know why it would all of a sudden quit sending and receiving. I did the latest update, it still don't work.
