Amazon removed Chromecast devices from Amazon.com and refuses to support Chromecast protocol from their services. They also removed Apple TV devices at the same time.
> refuses to support Chromecast protocol from their services
That’s a funny claim, considering Google intentionally has changed the protocol several times, to prevent any third party implementation of the protocol – including Amazons, and many Open Source libraries for it.
I was building an open source library for it when these changes happened, and I can tell you, it’s not pretty.
The only way to actually reliably stream to Chromecast, and to receive Chromecast streams, is with Google’s proprietary library for it. On Android, this is included in the Google Play Services.
Obviously, on Amazon Kindles, these aren’t preinstalled (due to their restrictive terms), so Amazon had their own implementation (which, as mentioned, Google acted against)
