Hi! We have released a workaround which does not cause lack of reflections and fixes the WebGL crash for Apple devices which were experiencing it. No suffix in the URL is needed, but your device may require a restart. We have verified it fixes the issue on iPhone XR and iPad 8th generation - both of them were experiencing this crash. Most Apple devices were not affected by this iOS bug, but all the remaining devices (older iPhones and iPads with iOS 18.2+) should be working now without any issues.
The workaround works for scenes that are hosted on our infrastructure only. If you are self-hosting them you have to wait for a new release and re-bundle them, so that they work on all Apple devices. We are planning on releasing a new version this week.
