Hey mist, small suggestion for the 'game settings' thread but perhaps useful: For Warzone, there is an additional controller setting exclusive to the BR called 'BR Button Layout' and this was set / overridden to 'Bumper ping' after the last update, whereas first it was 'Default' just like in regular multiplayer.
However, with the XIM mappings, this should be set to 'Default'. I am not sure this setting change is for everyone or even for new users but I did just now see a few posts about it on the forums (resulting in not being able to ping items in Warzone when using the XIM) and I had the same problem so it's possible.
