So for Facebook, I switch to the desktop site via the triple dot menu and it changes to the desktop site. But at one point, something does acrefresh of the page - I didn't select. It reverts to the mobile page. But when I click on the triple dot menu, it says I am using the desktop site. However, the page still is on the mobile site. If I go back it is still showing the desktop site. I turn it off but it slides back to the desktop menu.
