Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I'm trying to register it in my Amazon Prime Video account.
If I use the register on the Roku device, then then login to Amazon fails with an error message of "we are unable to complete your sign in. Please register on the Amazon website".
If I use the register on Amazon website, using the 5 character code, then I get a message saying "Success! Your device is registered to your Prime Video account." however the Roku still thinks the account needs to be registered, and the Roku isn't listed under my devices in the amazon prime video account.
The last attempts at registering where at about Monday, 28 May 2018 07:41:0 UTC for the register on the Amazon web site, and 07:49 for attempting to register on the Roku.
