Have you tried logging out? It usually works for me
I think you may have "Desktop site" toggled on in the site settings, you can toggle it off and you should see the mobile ver link again
It works!!!! Thank you so much!!!!!!!!!!♪ヽ(´▽｀)/
Noo, it's only when I read something it's in desktop version, other pages still in the mobile version. But thank god I can change it back by logging out first!
Accidentally set the reading page to desktop ver again, but this time, when I try to change it back by pressing the mobile version button from the profile icon, nothing happened. Then, when I scrolled down to the footnote of the page, there is no mobile version button. Does anyone have the same problem as me? ┗( T﹏T )┛
