404 Page not Found on Drawing practice pages [DEMANDE DE SOUTIEN]

I am getting a 404 Page Not Found when clicking on anything under the Draw tab. I tried in two different browsers. I am on a PC, Windows 11.  All the other areas of the website seem to be working.

That's very odd! I just tried all of them and they seem to be working -- have you tried a hard refresh (Ctrl-shift-R in most windows browsers) on those pages to see if you've got a bad cache?

I just had the same thing happen to me. But then realised that I hadn't verified my account via the email that was sent out initially. Give that a go, and it'll hopefully make a difference.
Good luck :)
