A friend and I downloaded Signal to try it out, and just couldn&#x27;t get anything to work. I&#x27;m on iOS 8, the app would just crash anytime I hit any button to make an action (send a message, even delete my account). On his end (he was on iOS 9), it said it connected to me, but his messages just got lost in the ether in between us.<p>I mean, I&#x27;m a technical guy. I don&#x27;t understand what either of us was doing wrong. Have you seen anything like this in your experience?
