Amazon has added casting support to the prime video app.

Why did they withhold support in the first place? I had assumed it was because they wanted to sell fire sticks. It's not in Google's interest to make Chromecast less capable.

This was honestly never a big deal for me because I could always cast from my browser on a laptop. But, yeah, I've observed that some of the Apple/Google/Amazon incompatibilities seem to have gone away over time.

I believe Google didn't permit FireTV to carry YoutubeTV because Amazon wouldn't sell Google Chromecast in their store (because it competed w/FireTV I guess).
