DatagramSocket not receiving packets in air 13.0 (iOS)

Hi,

Ik upgraded my air SDK to from 3.9 to 13.0 this week, and all Apps I created using the DatagramSocket don't receive data anymore. This only occurs in iOS devices, Android is still working OK.

If I run datagramSocket.isSupported I get "true".

What could be the problem here?

Thanks.

Kind regards.
