Hello - I'm new so please go easy... I have an issue that I couldn't find addressed in one thread that contained all the conditions I have noticed. I'm using an iPhone 4S w/ 7.1.2 OS. The other day I sent an iMessage to someone who has always used iMessage - when I sent, it started as a blue bubble, then flickered and turned green before the progress bar completed. The progress bar didn't stop or get stuck beyond the flicker and I did not get a 'delivered' after the message. HOWEVER! I have noticed I don't always get that 'delivered' notification, even though recipients have replied to me. I understand that when a message starts as green one of us could have iMessage off, be in a weak signal area, or the message was not delivered. But I also see suggestions that would indicate one has been blocked by the recipient - which I doubt, (but if I had I wouldn't want to keep bugging that person). I did not get a reply, but my friend may already be out of the country and not able to receive messages... I couldn't find any threads about the message starting blue but turning green mid 'send' - any ideas?
