When using an external keyboard and mouse on any xboxes: when one goes into the chat to either type a command or just to simply chat the xbox internal keyboard keeps popping up and getting in the way of previous features; when one goes into the chat overlay you can't instantly start typing(unlike in 1.18 or any previous versions) instead, one has to either  press the 'enter' key or click on the textbox at the bottom of the screen in order to pop up the xbox internal keyboard(in versions 1.18 or any previous versions all one needed to do was press the chat button on the external keyboard and instantly start typing even when the xbox internal keyboard is not on the screen), the tab button now doesn't cycle through the options provided above the textbox, instead all it does is pop up the internal xbox keyboard which gets in the way(this also was not a problem in 1.18 or any previous versions), moreover, the 'up' arrow now does not cycle through the previously typed out commands/messages, instead it AGAIN pops up the internal xbox keyboard which(you guessed it) gets in the way(in 1.18 or any previous versions this was not an issue), and lastly, when one is done typing out a command/message you can't just press enter for it to send, now you have to physically go over to the bottom right and press the send button(this is also an issue with controller players too). In conclusion, these chat "features" that mojang added are not useful whatsoever and are entirely useless and not needed and make it tedious for players that use the chat system a lot.
