Maybe problem with their servers.

I’d try again in a few minutes, and also check on other browser (or at least try to clean all the cookies).

I’ve tried multiple browsers, I’ve tried on WiFi and on 5G - I’ve tried multiple devices, and I’ve tried in incognito mode and with cleared cached.

Another user posted on Reddit with the exact same problem 16 hours ago - and I’ve been trying so far for around 2 hours.
