I have 12 cameras. I can view each of them remotely via web or app. However, on the "all camera" view, two cameras are missing. What setting could be causing this? It's always the same two cameras missing.
This was it, thanks! I don't know why I didn't think of this. The two cameras in question had previously had problems and kept disconnecting. So I must have marked them hidden. They both started working on their own again recently after I had some electrical work done at my house. They were without power for several hours, and I guess they decided to start working again afterward.
