I usually just use a new tab (unless it still stays the same which is odd idk)
it's on the right side there's a three lines click that and you'll find the mobile version (along w ur profile)
Try logging out then in again
I have an album for that if you want visual instructions

For your situation i think #2 will work, click the new version at the top when your reading a chapter of anything
does anyone know how to switch from desktop ver to the before (I think it’s mobile??) I was messing with the buttons while reading and accidentally click the desktop version and now the pages are so tiny and have empty space on the sides. I CLICKED EVERYTHING NTH WORK
