I already sent my reply too and the OP deleted their post lmaooo anyway that's nice ! me personally, I already wrote down my current reads, already reads and some of my want to read lists beforehand, so I just put all of those titles in my second account first, in case they're going to be back in this main acc of mine lol (it's been few days and only 5% of them came back). but I think I'm gonna give them a weeks or month, if they're gone forever, I'll just add all my stuffs back manually
Here it goes again
For ongoing stories you may have lost, go to the genre section. Select the genre and put "sort by: update". You can go back as many pages as needed and definitely find them
For miscellaneous mangas use the tag section. Just write any characteristic specific to the stories you usually read. "Animal characteristics", "office romance", "cooking", "disability", "pink hair". Anything goes, the more specific the better. The tag section is automatically sorted by popularity so keep that in mind
And talking about lists. If you ran out of ideas to find stories (or dont want to check 200 pages under a tag), check the lists that the stories are added on.
Lets say you searched "found family" and have too many pages to go through. Click on a story, click on a list that is specifically of stories with that plot. Now sort the list by "unread" and check from there
Is still a pain but you'll have to check max of 20 pages instead of 200

Guys I think I lowkey cooked - I just realised I could TRY to revive some of my ‘Reading’, and ‘Want to read’ lists, so I have some tips I want to share!! For the people who are desperate like me
1. Go to your profile and see if you’re FOLLOWING other users created lists- I literally just realised I’m following a few already, as well as some lists I’ve made myself back in 2021 to 2022?? I totally forgot about this tbh until I went through my profile
2. Check out your photo albums!! See if the manga/manwhas etc you were reading were on your ‘Currently Reading’ list.
Thats all I have atm, please feel free to share some other tips with us desperate folks - Also I’m not too sure if we’re allowed to actually touch our Reading and Want to read lists JUST YET! Personally, I don’t want to take that risk. So idk, I guess list them down in your notes for now ლ(´ڡ`ლ)
