Chat doesn't display system messages while in multiplayer

Entering cheats in text chat activate effect of the cheat but doesn’t display the corresponding message. This only occurs in multiplayer (Winddows 11 ↔︎ Android). For example entering the /locate command doesn’t show anything. An other example is the /gamemode command. The gamemode does change but no indication in chat is shown.
But missing right for using cheats is displayed correct.
