Why can Android send commands via NetworkManager but iOS cannot?

So I set up a game where portable devices sends information about what is pressed to an local server running on a PC using the NetworkManager from Unity's new Multiplayer and Networking.

• Both Android and iOS can establish a connection to the running game on my laptop, but only the Androids commands are recieved by the local server running on the PC.

• Both Android and iOS runs the exact same C# code.

I wonder whether I need to give some iOS specific use-network-allowing specifications somewhere.. does anyone want to share some helpful knowledge in this regard?

Many thanks in advance :)
