The last thing you need your security alarm app to be is buggy and unreliable, but there it is. Since they updated to this latest version, it has become terrible. More often than not, sending commands to arm or disarm the unit dont work. They time out with an error. Meaning, the sole thing you need it to do, doesnt work most of the time. Its always been buggy, randomly not working now and then, but for the last few weeks its become unusable.
