I recently had a Prime trial on amazon.com, to have some Christmas presents sent to my sister's address in Brooklyn. At the time I set up Amazon Prime Video my Nvidia Shield to take advantage of the trial. I now have amazon.co.uk Prime, but when I try to set my Shield up again to use it, it defaults to the US version. As a result a lot of the free stuff is not playing, due to my location. Other stuff isn't included with Prime, like Life In Pieces for instance. I've tried deregistering and reregistering the Prime Video app on my Shield, but it reverts to the US version every time. Has anyone a suggestion how to get this working properly?
