Bravia Core app will not launch. States a network issue and fault code INT-103-201. Navigated through the Sony support pages nearly all day following delivery of the TV.  Software and firmware updated, app updated. All other apps work and stream (Netflix etc). Signed off on Sony privacy agreements, successfully logged into Google TV with a Google account.
  There appears to be no page which indicates the current status of the app. Any ideas anyone? I’m about ready for taking it back to the shop.
