That makes a lot of sense for why it appeared stuck, definitely makes sense not to prioritize having a loading icon in such a short timeframe. I tried to recreate the issue from the other night but so far I can't. What it looked like was that the Score still showed '0' but had the real score posted over it. That was the full screened WebGL version, using Firefox on Windows 10. It's worth noting I've been playing it on hotel wi-fi and I'm getting better speeds today, so that may be a factor too.
