Can't send or receive photos in Messages since 11.2
I used to be able to send and receive photos in Messages fine for a long time. Since the 11.2 update from 10.3 (or whatever it was) I can't send of receive photos. If I try to send I just get the red ! and Not Delivered. I've tried various settings in the Messages control area to no avail. Also, when I updated, I updated Verizon carrier settings as requested. I've powered the phone (6s) down etc. too. No joy. Any ideas anyone?
Thanks
