"Footage Unavailable" on Indoor Camera

I have both the outdoor and indoor stick up cameras. My outdoor camera has been great and I love the ability to see previous footage throughout the day even when there hasn't been an event to trigger a motion alert. My indoor cam, however, only lets me view footage when something sets off a motion alert or I opt to check the live view. Whenever I go back through the history everything is blacked out and it says footage unavailable. Does anyone know how to fix this? I have tried to reinstall the app numerous times but this didn't do anything. Thank you.
