Casting from my Kindle Fire

For Kinde Fire, I use Allconnect from the Amazon app store. It's free. It finds my fire sticks and my rokus. It doesn't find my chromecast.

Allconnect even lets me cast from Plex, which we all know doesn't seem to find casting devices on Kindle Fire. This Plex bug is the reason I installed Allconnect in the first place.
