Reading list is gone!!!! (⁠ᗒ⁠ᗩ⁠ᗕ⁠)

Why is my whole reading list gone? Are the devs doing smth? I hope it's gonna be fixed. I shit my pants when I saw 0. Even logged out and logged in again and still showed 0. Devs I hope you will reverse this, I had over 300 saved.
P.S. also tried to save the manga I was reading just now to my reading list and it didn't show up.
