Button not working Xbox one?

So the LT button on my Xbox one controller won't work on Minecraft, but it will work on every other game. Is there a way to fix this?

Elder guardian likes me? Minecraft 2018 xbox one?

I know this isn't the place to ask this at all.
But I'm playing minecraft on creative mode (easy) and I have come across an elder guardian.
I was curious because I've never seen one before so I grabbed a diamond sword to start killing it. But every time I hit it, it throw out little heart like being tamed.
I tried it with regular guardians and that did the same. It flew off hearts and then settled somewhere else to stare at me?
Are they just masochists? Or is it a glitch?

Do you need Xbox Live to play Minecraft multiplayer?

I know this is a silly question, you need Xbox Live to play any online multiplayer games on Xbox. But since Minecraft just released a new version that's supposed to be compatible with the Better Together update, do you still need Xbox Live to play online, considering PE and Windows 10 users don't have to. I usually play on the PC (more like exclusively), but if online multiplayer is free, I might give Xbox Minecraft a go. Every Google result for this is just asking about the Xbox 360.

Minecraft for Xbox 360 there's NO 2x2 crafting table in my inventory menu so I can't make anything at all

Minecraft for Xbox 360 there's NO 2x2 crafting table in my inventory menu so I can't make anything at all!

Added (1). I'm new to playing so maybe this is a simple fix but I played on my friends Xbox 360 and used the 2X2 crafting table in the inventory menu to create simple things like planks, sticks and a larger crafting table. However on MY minecraft game for Xbox360 there's NO crafting table when I open my inventory. When I click "x" to open the "Crafting" menu I also can't select the ingredients that I have in order to make planks!
