Phillips 65pus8536.

On 90% of occasions when trying to launch some streaming apps, a message appears reading

'Offline, the TV is not currently connected to the internet. Click 'Connect to restore or setup your network connection.'

The TV IS connected to the internet and it still happens with both wired/wireless connection. Some apps will work whilst some do not. Clicking connect does not fix the issue. It only appears to be the smaller UK streaming Apps are affected like ITV hub, BBC IPlayer, My5 and All4.

Netflix, Amazon, Disney, YouTube, Apple TV and crunchyroll are all working fine.

Tried Hard reboot, factory reset, clearing app cache and router reset, none of them fixed the issue.

Thanks for the help!
