mgg only gives u notifications twice a day, for example mine is 9 a.m and 9 p.m. If a manga updates during that time period,for egz if my notification time it 9 p.m and the manga updates at 10 p.m, I will only get notified tomorrow at 9 a.m
They update based on your timeline, the first commentor is right. Mine is between 6:30 AM and PM tho!
I do recommend looking at your notifications' recent time and previous ones so you can know what the site usually notifies you
Wow I never knew that they have specific timing even tho ive been on this site since 2020
For the manhwa and mangas that were updated they haven’t notified me and I see that the are updating (sorry if grammar is bad I’m sleep deprived from working on my two papers)
