It's been two weeks since Codeforces, for some reason, started recognizing my PC as a mobile phone and switched to the mobile version. This is very annoying, and I'm wondering if I'm the only one experiencing this issue. Can anyone help me fix it? Here's how it looks:

The problem disappears when I use incognito mode. I have tried to erase cookies but it doesn't work. Switching accounts won't work neither.

Thank you!
