The intermittent issues on this app keep it from being top tier. I get very frustrated when it doesn't notify me or update message statuses. The only way to resolve is to close the app and reopen. I was on a call today and I wanted to send a message. It would not send and it deleted my message. Then my system UI app crashed and I restarted the app and it still didn't work. So I had restart my whole phone. What gives? I'm trying other apps.
