So thanks for tipping me off to the existence of this app. It generally works on my 49XD8005 Sony TV, and I watched the To Live and Die on Murder Island livestream on it.
Two issues so far though - it crashes and has to be restarted every time switch back to it after having turned my TV off. I think I had the same issue with the Crunchyroll app, possibly related to the newest firmware update. Also, I don't know if this is related, but it often seems unable to find the newest videos. Right now the archive of the Murder Island stream is available on the phone apps and the Kodi plugin, but not on Enthusiast. Had the same issue with Exquisite Corps 3 yesterday, which finally showed up today.
Also working well on my Sony KDL-50 Android TV apart from it crashing more often than not when exiting the app.
KDL-50W805C running Marshmallow.
