How can I add pages from manga while reading to my albums ??? (￣∇￣")

Depends on what view mode you're in, and also if on you're on a phone or computer.
If you are in "scroll mode" and on a computer, just click the page you want to add to an album.

So it doesn't work if I'm on a phone....

not sure how it works on phones, sorry

OK thanx(⌒▽⌒)
