There is no easy way to know on which AP an SSID is visible. I have some AP in a network policy, on which I disable some SSIDs . I would like to have the possibility to show that list and modify the SSID availability in a batch
You could clone your network policy and then remove the SSIDs that you don't want deployed in the cloned policy. Then for the APs that you don't want the SSIDs deployed to, apply that new policy to them.
