@BrechtSchamp is correct.
Now I want to lower your expectations. The app hasn't had any development work done on it in a long time. There are frequently complaints about it. Support can't do much about it.
It will probably work fine for what you want ... but don't expect it to be of the same quality as the rest of the Meraki solution.
Why is that? I thought the security camera line was really taking off? I would expect some love to be given to mobile apps for it
It's just the app in general that needs some work. It's meant as a mobile version of the dashboard to monitor all your Meraki equipment, not just the cameras. One of the possible explanations is that the team responsible for the app has been too busy with Meraki Go.
But to watch the cameras it works fine.
