Very interesting! Do you have anything disabled in your browser? I've only ever seen that when someone was blocking JavaScript. What device/browser do you use? Can you try another browser?
browser is called Safari and it default browser for IOS devices also I tried another browser (by downloading app for it) but that didn’t work. JavaScript is enable for Safari. IOS version is 15.8.5 since that also effect seem to affect safari version.
This is useful data. I'll try seeing what is going on. I wonder if it's got something to do with local data being blocked or some other option. Regardless, the game shouldn't just be stuck at a blank screen.
