Did I miss something? Did something change lately? Your apps have been awesome on my machines and I really appreciate all that you've done. I'm just wondering what made you decide to leave? Your youtube runs perfectly on my pendent ftv3. And launcherhijack was just updated to work on it as well!
yes with new hacks and workarounds again and again it may go on for a while, but the way Amazon enforces its restrictions is no longer tolerable for me. With my Mi Box S as an example I have the newest ingenious Android TV 8.1, all apps work including YouTube, YouTube Live TV & Amazon Prime out of the box and you don't have to modify anything at all. Any app you don't need can be deactivated or uninstalled at any time. And about the high quality of Google Assistant compared to Alexa I won't start now...
And you don't need sideloading any more, it's all in the Google Play Store, Kodi, etc..
And faster than any Fire TV the Mi Box is also, both in the menu, and in Ultra HD with 60fps. Amazon's strategy of wanting to be like a closed system like Apple TV is ridiculous. It has only disadvantages, I really see no reason to buy a Fire TV again and then modify it.
