maybe check if you really subscribed, if you are, then you can always go on Mangago's profile to ask why you aren't getting notifications

You don't get notifications for the mangas you "want to read". You get notifications only for the mangas you "already read" and " still reading"
You do not have any manga you already read as i see and very few manga that you are still reading. So i believe you dont get notifications because there isnt any update since those three days.
i am not getting notification ,even though i didnt do any thing to be restricted ,this is my first post!!!
