I had that issue after it "verified I'm a human", I refreshed and it looked fine.

I have refreshed a few times and the styles still aren't loading

It's pretty good on desktop. Report the bug and I'm sure they'll get to it

The CSS bug happened to me on desktop too (but went away after a refresh). It looks related to Anubis since the reason the stylesheet isn't applying is that it has HTML containing "<title>Making sure you're not a bot!</title>" prepended to it.

How fascinating, the exact same thing happened to me!
