Issue with widget background colours

My widget has reverted back to the white colour or background despite having deleted them and changed the settings like I’ve done in the past. And opening the app and restarting the phone doesn’t work or change anything. It’s not a huge issue I was just hoping to make you guys aware of this so it can be fixed and sorted out. And also I wanted to note I’m on an iPhone 16 pro max on the newest iOS, 26 with no beta software. Thanks
