I used to read mangas here during the COVID period.I used to sort out the mangas by using the tags like "want to read", "reading", "already read". I stopped reading mangas in 2022. Now I am back here but I realized many of the mangas that I already read and want to read are missing from the list, And all of those which I tagged "reading" are gone. The "reading" list has no mangas that I tagged!
What can I do to fix this problem?
