Issues with group messaging
Yesterday evening my group messaging quit working.... up to that point 4 of us (3 of which are also iPhone users, the other is a Samsung Galaxy) had been trading messages all day (and for months) then last night my last message would not go through. Today, all messages in the group are erroring with "not delivered". I've done nothing different. I have an iPhone 5 and updated to ios 8.3 as soon as it came out (several weeks ago I think). Again, had no problems till last night. I've tried numerous suggestions found on-line... short of resetting to factory settings because I've done nothing new prior to issue starting and, though I did do a backup, I don't want to start all over if this is an update issue that may get resolved with a new update.
iPhone 5, iOS 8.3
