Good day, I have two suspicions of what is going on:
- Either Gamepad A is pressing a keyboard focused on-screen UMG widget. Gamepad navigation lets you navigate UMG menus with directional buttons and pressing a menu button with A. If the game’s input mode is Game and UI, that’s what might be consuming A as a UI action.
- Or CommonUI might be taking the Gamepad A input and processing it as a mouse click.
Both are issues that have been reported in the past. Do you know if any of these two explain what you’re running into?
