Until recently the app hasn't had too many issues but with the update of the main tablet that kept on freaking out with constant restarting now the app is having trouble with arming you know the main function the app has the app is buggy and can't tell if the system is armed or not anymore it can arm it but it will say it failed but still arm but also say disarmed now I am having issues opening the app and now viewing cameras is slow at critical moments it fails at its main purpose
