Custom CSS disappearing on mobile view

Hi,

I spent yesterday formatting this page (and others) using additional CSS. Everything was fine when I logged off, and the content was formatted across all devices. Today however, whilst everything looks normal on desktop view, the mobile view has reverted to its old formatting!

For example, on this page, the heading at the top of the page (‘North Norwegian fire meets Japanese finesse’) and the one just beneath it (‘Angelita Eriksen’) look correct on desktop view, but if you shrink the page to a tablet or mobile size, they both revert into a different font, the padding around the first heading increases and the second heading switches to upper case. These are all things that I fixed yesterday so I really have no idea what’s going on.

I deleted two Plugins today (Imagify and BackupBuddy) and updated the TwentyThree WordPress theme. I’ve also added a few other bits of additional CSS on another page (lofotenseaweed.com/chefs-collaborators) but I don’t know how I could have scrapped all the formatting on only the mobile view.

Any help would be greatly appreciated!

Thanks

Steph
