Can't access setting

Came home from a short trip and cameras work, but can’t access setting. Says cameras are null. Garage door cam was there in the app when I got home then it was gone, now it’s back but still cant access settings. One cam light goes from red to blue then back to red etc.

If the camera light is alternating quickly between red and blue that usually means it can’t connect to your wifi. Try rebooting your wifi/router, and possibly the cams after that if needed.

What happens if you try clearing the app cache and restarting the app as described in another topic?
