Group Message does not work with Beta 4?

[Zorn]

I have a 42 person group that I send mass texts to for invitation purposes, and as of Beta 4, when I go into that thread, it claims it's an iMessage, and will not send anything. The send button is blue, but "greyed out" so to speak, such that when I type in it, I can't send. Anyone know if this is a beta 4 issue, or why I'm not able to send a message to a group?

As has been mentioned many times across threads, and by Apple, don't use a beta on a device you need to operate at 100%. Things are always being updated and broken on the beta. Try going back to OS4 and if it solves the problem.
