Group sms messages won't send
Hello, I've been trying to send group sms messages on my iPhone 6 and they're stuck in "Outgoing". I've carrived out the checks as per the Apple help section and the phone numbers are correct. However, in my settings under messages I don't have a "group send" option to turn on/off. It all used to work fine....
Thanks in in advance for any suggestions.
