Camera not working when not on the same wifi network

The app used to work however with this new update, the app and cameras do NOT work when I am not home. When the app and the camera are on the same wifi connection it works fine however as soon as I leave the house, the app stats that the device is OFFLINE. I purchased the cameras for when I am NOT home. This is useless if I cant use it away from home.
