I think i accidentally switched to desktop mode,anyone know how I switch back

are you on ios?

scroll to the bottom, there is small text saying "Mobile Version" and you can just press that

click on the three lines in the upper left corner, there shoukd be a button saying monile vers

I'm on android. I just tried scrolling down and looking on the upper left and I don't see an option

it's on the bottom of the screen, it's where you would usually see the site credits

Fixed it now thank you all

this could help if you’re new to mangago or is not super used to the features of it
