Unfortunately the issue still persists. We will work on possible fix asap. Meanwhile you could add #nobasis to the end of url to load the scene properly on iOS17
So instead of:
https://demo.shapespark.com/demo-room/
End link with #nobasis
https://demo.shapespark.com/demo-room/#nobasis
Or combine with other parameters with ‘&’
https://demo.shapespark.com/demo-room/#autoplay&nobasis
