I use excalidraw for school and I'm trying to publish my notes so other classmates can check them out. I use excalidraw a lot and I'm trying to have the drawings auto-export and auto-update the images exported, then show the updated PNG related to the drawing. I think I have everything enabled, but when I press the save icon in excalidraw it'll create a .PNG file with the same name but the issue is it's an empty PNG. There's nothing on it.

Has anyone encountered this before? Any help is appreciated. Thanks!
