Chess.com layout changed all of a sudden!

The layout of chess.com just changed all of a sudden. The layout had all of the play, learn, share, home, etc options of the left side of my screen. Then I right clicked the facebook icon at the bottom of any chess.com page, and opened in a new tab. I saw that the facebook page had a "play now" button. I clicked that. Then a miniature version of chess.com opened in my facebook browser, except the layout was different from the website. Then when I went back to the website, I immediately closed the facebook tab, and I clicked something, probably "play" and when the page reloaded, it was in the layout on the facebook page, with all of the options now being on the top of my screen instead of the left. I do not like it this way. How do I switch it back?

so I just cleared my cache. I got the idea, half way through writing the topic... sorry lol. Should I just leave this here to help others? Is there even a way for me to delete this topic?

V3 used to offer a choice between the top and side menu. Lots of people accidentally moved the menu from the top to the left and vice versa.

There was a menu icon to move the menu. I guess they have removed it now.

So, I just found the button you are talking about, but that button was not there, nor was the top menu layout, that I can toggle to using the button, the menu layout that I was stuck on. If you go to the chess.com facebook page and click "play now", that is the layout I was stuck on. There is no button on that layout.
