i was able to make the manga library work by using my username instead of my email address when logging in on the app.
the screenshot i posted a while back was using my email address logging in on the app and it was not displaying my manga library, tested it by logging and and out using my username and email address simultaneously when logging in.
i was asking if they can be on one tab because of this one back then hehe
if you can remember i asked back then if the anime banner on top of the library can be removed to have additional screen estate because it is already indicated below via the tabs that you are at your library
i prefer a separate tab btw, it's much accessible, although renaming the other anime to popular (or i dunno what to name it coz it has the charts in it) to avoid confusion with the anime library tab.
