All Mangas Reader

Sorry i don't know where to put this.

So lately i kept getting pop ups of those notices that tell you that a manga has a new chapter, but when i go check it, i wasn't even updated at all. So i would just mark it as 'mark as already read' but one day i came on and my whole list of manga did the same thing, but none of them where even updated. So that messed up my list a lot.

Also, lately my amr isn't working at all, it isn't changing the manga chapters into one whole page, like i can just scroll to get to the next page of the scan. And it isn't marking my chapters that i have read them in my AMR list.
i'm thinking of just redownloading it again but i don't want to go back and go through all the manga i've read, i know that you can sync your manga but you have to have a list already provided. Is there a way for AMR to display all the manga you've read into a page or something?
Sorry i sound really confusing.

Well I think you list gets saved if you uninstall and re install, I did it before. But if your manga is from mangafox you can read how to fix it in the faq. and what you described is what happen to me when mangafox changed their URL

Blankzo is right, just follow the guide on the FAQ and you'll be able to fix up your AMR.
