The button with 3 lines. Click that and you should be able to select mobile or desktop version. Good luck! It happened to me once as well.
The unfortunate part is, I don't have those lines. They're not only top left nor top right
Maybe click on your profile? Sometimes it will provide you an option to switch but I'm not certain
Thank you for your help...It turned out I accidentally pressed desktop mode on the settings of the browser...
How do I change back to moble mode on a phone if I somehow turned it to desktop?! I'm in desperate need for help
