People can't see my messages in chat and vice versa

At first I didn't really noticed it and thought people were just busy "playing the game" when really this has been happening ever since I got the game, and for some reason I can talk to the realm owner but never to anyone else?? And anyone else that is not the realm owner also can't see my messages, would really appreciate any help I can get on this! Getting tired of having to go back and forth between the game and discord.
