As title, can log in and see my watchlist etc but when I click on a video it says it's unable to play, please see www.amazon.co.uk/videohelp (have tried all suggestions) and sometimes it says I don't have enough bandwidth but 4K Netflix works fine on Shield and 4K Amazon Video app works fine on LG TV.
The app used to work fine when first was available as part of the nougat update but wasn't working just before the 5.1 update and still not afterwards. I've tried deregistering my shield TV, rebooting and registering again but no joy.
Anyone else seen this problem before and maybe know how to fix?
