Hi, I have found a bug, I hope it has not been already mentionned, I didn't read carefully the whole thread. As the email doesn't seems to work, I explain it here. When I close the app by a swipe down and then I close the wifi connection, I am not able to reconnect again: when I open the app again and I open the wifi connection, it is always marked "Offline" and I cannot send or receive a message. For resolving the problem, I have to close the app by the "Quit" buton and then I have to restart it. Only by doing this, it works again. Thanks again for this great app.
