Trouble sending group text message to one particular group
My text messages cannot be delivered to one particular group (myself and 3 others). One of the other members does not have an iPhone. I did not have this problem until a week or so ago. I am able to send to each of them individually (including the one without an iPhone), but just not when it's a group. I have this issue whether I am using my phone, iPad, or MacBook. I have SMS and MMS turned on. I am also in another group which texts frequently and not everyone has an iPhone, but do not have this problem in that group. Any suggestions?
