Got iOS 9 public beta the other day. Most things are working really well, but I've noticed trouble sending iMessages while on Verizon LTE. They get stuck at "Sending" Have iPhone 6 Plus. Verizon. When I'm on wifi, it almost never happens. When on 3G, no issues. When sending as a text message, no issues. I've narrowed it down to just when I'm on LTE. Anyone else having the same issue or know how to fix?
