I saw a similar post before, according to what they said mangago sends notifications twice a day for example like 10am and 10 pm or 7am 7pm etc. If a manga updates during the non update hours you won't get notified until th time comes, for example if the update time is 7am and 7pm for you and if sth updates at 7:30, you won't be notified until 7 am. But it seems to be taking longer than that for you

Has anyone encountered a problem where the updates aren’t showing up? I have a few mangas/manhwas in me “reading list” that have updated but I didn’t get notification. Usually it takes a day to update since upload but it’s been two?
