Fire Tv Cube won't sync to video

Hue essentials is not syncing video from any sources on fire tv cube. It works flawlessly on my chromecast with google TV; however I can not get it to sync from any sources on my fire tv (not just DRM content). Is there something I’m doing wrong?

This is a known issue with the Fire TV Cube, we are looking into it. See also: Hue Essentials on Amazon Cube

With the last update it works on my fire tv 4k stick for first time, can anyone test it on othe amazone devices?
