Apple registration page issue looks like a CORS issue. Chrome also doesn't render those question mark signs properly (also CORS issue). Safari, however, loads it with no problem. I checked http requests, and I think the only difference is, Safari makes the request with no-cors while both chrome and firefox makes it as cors. I'm not sure if this is the reason, but at least the Apple registration page is about CORS and not about FPP.
