I like to apologize to the devs for my idiocy for adding more work for them when they already swarm with works. I hope everyone get enough rest when working on this glitch.
Again I'm so sorry for adding manga to 'want to read' 'Reading' and 'Already read'
You're ok. People are getting too touchy about this. If the devs didn't want you to add stuff to your reading list, they should've kept that function shut off. I do recommend waiting a little longer to see if the lists fix themselves, but if you don't mind the order being different from before, adding things back is probably fine.
If you don't want to touch your reading lists, you can use the mgg bookmark function. As far as I can tell, mgg bookmarks are working perfectly fine and have not been affected by the reading list problem.
To bookmark a chapter/page on mobile, open the chapter/page you want to bookmark and hit the button at the upper right corner with three horizontal lines. A dropdown menu should open and you should see something that says "bookmark it". Hitting that button will bookmark that chapter for you. On desktop, there will be a button on each chapter/page on the upper righthand corner with a heart and text that says "bookmark it".
To find your bookmarks on mobile, get out of the manga, click on the button with 3 horizontal lines. You should see a text in the menu that says "bookmark". On desktop, you can click on your pfp on the upper righthand corner and you'll see a "bookmark" option on the menu. You can also see what pages you have bookmarked if you go to that manga's homepage. So if I have chapter 24 bookmarked on Our Sunny Days, I can go to the Our Sunny Days manga page and it will show that I have chapter 24 bookmarked.
Ah, I forgot to mention that you don't get update notifications for manga you "bookmarked" and I believe there's also a limit to how many bookmarks you can have on mgg but I don't remember the number. So that kinda sucks but bookmarks should help you keep track of what you're reading until they get lists corrected.
When will my 'Want to read' 'Reading' and 'Already read' come back, I'm not complaining, just paranoid, scared that I'm going to lost hundreds of manga. With the oldest manga site got deleted that makes my anxiety even worst. I added some 'want to read' manga and when I do, the thought of it overwriting the previous save mangas make me fear the worst
They aren't deleted you'll get them back.
don't worry, ppl whose acc were made in 2014 and 2015, as in earlier years, slowly got their reads back.
Currently users who added stuff before February 2022 are getting their reads back. It wont all come back instantly but slowly one by one.
Here's proof of accs who've gotten their lists back :

so yeahh it'll take quite some time but you'll get them back.
also once they're back, in case you're looking for ways to save them perhaps in an excel file, I've made a tutorial on how to do it easily and quickly rather than having to enter everything manually one by one, so if you'd like, you can check it out.

Can I booklist now?
Yeah
I see people saying they have had no issues, but other people still are. Just be more careful.
Make sure you check each entry goes into your lists. Go to your lists page and refresh ~20 seconds after adding it to see if it goes in properly. I say also add it to your browser bookmarks or favourites in case. The site isn't working as it should sometimes so just be more careful than usual.
Another issue I've seen is not being able to delete stuff from your list. I talked to a user who couldn't delete something from their list on March 4. I followed up and they still can't do it on March 8.
I personally advise against it, but that's my opinion.
