Have had for less than 6 months. It worked ok, despite all the annoying uh oh messages. But now every time I touch the app to open it, it opens for a second and shuts down. I have to open it twice. I'm also not getting notification sounds. Yes, the settings are correct in my phone and app. Finally, there does not seem to be a way to add a second person who can fully use the app. I called lorex and they had to log in as me and do it, but it STILL won't work.
