ios App not working suddenly

What is going on? I see a bunch of people reporting the same issues. My app suddenly stopped working, and my cameras all disconnected. I can't log into the app - says "connection error try again later." I can't reconnect the cameras without the app. I am dead in the water here and paying for a service that I'm unable to use?? It's too late to call customer support. This needs to be fixed ASAP. Please help!!!
