Hello all, is there any way to change the timezone of the F-series TV (I have an F-5470) when in the UK or another country that only has one timezone. The reason is that I am usually in the UK app store, as this is where most of my apps are located, but I have merged apps from other countries. The TVNZ app only works when in the New Zealand time zone (just changing the clock doesn't help)

I used to be able to change the time zone, but that has stopped in recent firmware updates.
