Not everybody lives in just one country now, chaps! I didn't say it didn't work.
I should especially be able to install it when I'm in the Netherlands. But I should be able to install it from anywhere. I can understand it not working outside the Netherlands, and I'm fine with that (same as the BBC iPlayer only works in the UK).
Why is the Ziggo Go IOS app only able to be installed from the Dutch AppStore AND when you have a Dutch AppStore account? My AppStore account is in the UK, so I cannot install the app (you can't have 2 accounts for the same Apple ID, AFAICT).
