Setting up on different devices, which are in my opinion much too late in a sufficient number of different producers (in my case Samsung), is far too complicated and it repeatedly occur conflicts. It must constantly be downloaded extensive updates. This is so not fun !!! Here is a good idea is unfortunately made to naught and sold expensive. I order quite a lot still to Prime worth still, but the extra charge for instant video is not justified in my eyes, as long as that does not run smoothly as usual everything I had to do with Amazon. Too bad for me as a movie fan! I hope for improvement or repair on price fFor longstanding Prime customers!
