Cloak ?

Does the Cloak system works?!?!?! I developed the tech, and my ships & fleets have the icon to activate the cloaking system, but when i tap it the game says "activating system" but nothing happens...no change in icons, enemies still see me and if i tap again the game says "activating system"...AGAIN...How it works?

Thanks

If you look at your ships in the listing they should dim. If you have an enemy that has a cloaking level the same or higher they will be able to see you.

i know it had to work that way, but i've triy also with player that are inactive from the very first days of the server, so they have not developed any science of tier higher than 1. They still see me and my ships...and automatically destroy them. But I repeat, when i try to activate cloaking nothing happens, no visible change in icons or in descripitions...and if i tap again the cloak button it always say "activating". (server Mareth)
