As confirmed by Helen herself in an email to ibxtoycat, Minecraft: Apple TV Edition ran into a bug in 1.2 which affected saved games. Instead of holding back the whole update, they decided to bring the update to other platforms until they got the bug worked out. It's a difficult bug to fix, and as of this email, they've been deploying more devs to work on it. If the Better Together update still hasn't been released it's because 1) they're still trying to fix it, or 2), which is very unlikely, the project has been abandoned. As previously mentioned by a moderator, the correct place to be complaining about it is in an email to Mojang Support. If you want to play with someone right now, the Better Together update is on various other platforms. Xbox and Switch also support split-screen multiplayer if that interests you.
