Remote play - Minecraft issue (controller input not registering on menu screen)

I did a full reset of the console and there is still 0 action on menus an in games with both Elite Series controllers Ive tried. Both controllers register input in test screen as well.

I randomly got the controller to stay connected. When I open the Xbox App it says "This controller is connected via Bluetooth. Connect a USB cable to configure it." When I click on the test button, none of the buttons are registering inputs. The "Game
Controllers" settings menu just lists a generic "Bluetooth XINPUT compatible input device" and does not register any inputs there either.

You can definitely play DVDs on that or any other 360 console.

For the issue where the DVD is not filling up the entire screen, you can change that by pressing the 'Display' button if you own one of the 360 DVD Remotes or pressing any direction on the D-Pad on the controller to bring up the menu while it's playing and
then going to 'Advanced Controls' (looks like two gears).

Either way, you'll bring up the Advanced Controls menu and there is an option for 'Display Mode' (picture of the rectangle) in there that you can use to change how the DVD is presented on the screen.

When your console is on and you open smart glass, in the bottom right corner is a remote icon press that and you now have a remote to control the X1 home screen and menus and use as a keyboard.

I'm pretty sure at this point the issues with the A button is a hardware failure, as the controller frequently just doesn't register an input when the button is pressed. This is really visible when you have to press two buttons at once, such as A and X,
to perform two independent actions simultaneously, and only the X input does anything. It might take several presses before the A button does anything.

Regardless of what the issue really was, I can't test anything further until I get a new controller, as this one is definitely broken. The hinge on the right trigger broke (doesn't prevent use, just makes it feel gritty), I'm having issues with the A button
as described above, the d-pad is registering double/triple inputs (makes menu item selection quite the chore, especially when the software developers make the menu reset to the start when accidentally navigating to a different menu), and the USB port won't
hold the cable anymore.
