Last night i was using the scribble on my iphone 7 and was sending scribbles to my girlfriend. After that my imessage started not to work. Since then I have been sending texts as SMS message and not imessage. I called tech support they do not know the reason why it is messing up. I had to stop with tech support to go into work but they're calling me back after work. Just wondering if anyone else has an imessage issue.
