Well, I with the latest CVR app, and a scenario published earlier today, on my older iPad and my brand-new iPhone XR, I get the spinning cube and then an almost immediate crash of the app when I try to launch.
The old scenario still launches to the black void of space.
As an experiment, I published your Corals of the Caribbean scenario with CVR 10 minutes ago (so the latest version) to my own CVR space. Launching it on the iPad results in the weird jitterfest effect I posted above. Launching on the iPhone XR results in the black void of doom.
