Spline scene not showing in mobile mode

I’m new to all this tbh just want a simple site, but i noticed that the spline 3d scene is not visible in mobile mode…its visible in others modes and i can adjust it to my liking later. I think it was visible in mobile mode before i added the “portfolio button” … and the spline scene also has a grey background for some reason although i have hid the background while exporting the spline scene. if u guys know lmk thankyou!

here is my read only site
