Not getting update notification!!

it is not common. maybe try double checking any settings or https://www.mangago.zone/read-manga/mangago_how_to_guide/
i usually get the notifications a few hours later after it updates but it is usually on the same day it was uploaded.
If nothing works and this continues try emailing mangago

I emailed them and commented on the guide acc..Hope they get it done soon..Thanks for helping me..(▰˘◡˘▰)

When you add a new manga to your reading list there is a checkbox that says subscribe this manga. It's right under where you rate it make sure that this box is checked or you won't receive notifications

i, too, had this problem two weeks ago
