Hi, I'm also missing some of the IVAO centre online control areas showing in EFB. I've downloaded the latest IVAO files from the downloads section (dated May 2 2013) and changed the display unit setting to point at them (the default setting of pointing to 'The Eye' is no longer valid as IVAO don't support The Eye any more and only support 'Webeye' instead).
Is there anything else I need to do?
TIA
Richard
