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.
Just because Amazon Music is available on other platforms doesn't mean it's available on Roku devices. Roku doesn't control what channels/apps are available in a region, the developer does. You should reach out to Amazon and ask them why Amazon Music isn't available on Roku devices in Germany.
