I am having a similar situation with prime video. Trying to watch the movie Dr. No but get the error when trying to play it using roku device. The trailer plays fine. The movie plays fine on PC, phone tablet. I have restarted the roku, unregistered and registered it. I have seen this issue with any other movies or shows. Any ideas?
I am having the same issue with Amazon Prime Video on Smart Samsung TV. Can play video on my phone, just keep getting error “something went wrong” on TV. It appears to be loading, then buffers, then error. I have re registered it, and tried choosing Resume. Nothing works.
