Chat not working on Xbox with external keyboard and messages not showing up in realms

Wanted to play some Minecraft and tried to type in a command (i use my external keyboard for that), and it didnt work. 

Every other action did work though with the keyboard; walk, open chat, hotbar, etc.

For some reason others in realms dont seem to see my messages in the chat

I found some old posts that said something with the Privacy Settings on the Xbox, tried that and its still the same

My chat isn't muted either...

Any suggestions on how to fix it?
