Two sets of cameras in two different locations

My same question and situation are the same as David_Laney July 19. I have a set of cameras at one home with a separate module from a second location. The camera added to the second location with a different wi-fi and module was sep up and acknowledged by the app, but the camera does not show up on the app. (Austin_Cox Jul 19) The two existing cameras are still visible on the app. What might be the issue with the single-camera, and why does it not appear on my app?

Cameras are listed under each sync module (system).

Did you first select the sync module controlling the camera?
