I have a bravia fully connected to the internet and can use iplayer for example. However some apps like itv x try and connect via youview. 

I have no cable or satellite,  WiFi only.

The youview app does not provide options to tune calls via WiFi. 

How can I get youview setup so its x works via yoyview OR configure the itv x app to use WiFi and bypass youview all together.

Both apps are built in to the TV and all software and apps are up to date.
