Okay let me get this straight..

It'll probably be on tomorrow's notification, it updated after today's notification

This story is ALWAYS updated on Wednesday and we get the real notification on Thursday. You can ignore notifications on any other day, since the translation is caught up with the raws.

Even so why does it notify me so many times falsely. It is so annoying. No other manga notification do this for me

There's been some false updates, for example ch 101 updated before than it was supposed to and I checked it out just to see that none of the pages worked. Now I don't know how or why or who posts these false chapters, whether it's mangago's careless mistake or some idiot sends "a new chapter" for mangago to publish just to get it taken down because it's somehow wrong or doesn't work. Has happened to me many times with many different mangas, the most common mistake is that already completed manga gets an extra chapter which is actually already at the end of the last chapter and then it gets taken down before notifications come out. Then people who get the notification go and check out the manga just to see that there's nothing new - since the wrong part got taken down.

True, it has been happening often. Many of the stories I follow have been having this problem.

Sometimes it may be because the chapter that was first posted had cuts that made it impossible to read if you don't use multipages, which is not available for readers without an account. So someone re-posts the chapter with a better format, and the old one gets taken down. But we receive the notification anyway and it looks like a fake update since it's an old chapter.
