Mobile site showing on desktop. How to switch
 

For some reason Chrome recently started loading the mobile site on my desktop. Is there a way to manually switch to the desktop site?

same here. no 'return to classic site' option at the bottom of the page, nothing in user settings. Chrome user also.

I am also looking for help here.

I can switch to 'Fullsite' on my mobile, but my desktop chrome is stuck on mobile.
