2nd X-BOX ONE remote controller cannot play in Minecraft Dungeons

Followed instructions but nothing happend. The game was set to offline, left stick clicked down and neither split screen appeared nor second remote controller can be connected...

So after starting the game press A and Select the profile you are using Then when you are on this screen On this screen with the second connected Controller click down the left stick then player two will be connected.

then you’ll be able to play

Just to add to NXP1 reply, you cannot use split-screen in an online game it has to be an Offline Game. When you on that screen where you add an additional player you need to press RB to change it to Offline Game.

I am sorry to hear that.

This may be an issue with the Steam Deck.

On your PC, are you using the Xbox PC App for remote play?

I think thats a little misunderstanding. The One can not react on the remote commands from your cable or tv remotes at all.

The One is able to send these remote commands itself and act as a remote control that way. So you are able to use smartglass as universal remote to control your devices via the One or use voice commands to do the same with the kinect. But you cannot use
your remotes to do anything on the One.

Of course you can use your remote controls to send commands to the respective device even if the One is configured to control them. It's more like you can choose to control your TV and cable box with the One (with Kinect, Smartglass or controller ) AND/OR
your usual remotes.
