Sometimes an uploader will upload a new chapter after the usual time you get notifications so it wont appear in your notifications until the next round of notifications it happens to me sometimes but I recommend you keep up with the new updates on https://www.mangago.zone/list/latest/all/1/ it shows the most recent uploads
Whether I got the notification or no, I always list the name and latest chapter that I read to keep it on track. Just in case something unwanted happen, especially back then when the history is not recorded and I accidentally deleted the browsing history (╯°Д °)╯╧╧
Bro I have many mangas that I am currently reading and thank god I wrote done their names in notes because I’m not doing notified of all the updated is it because I’m reading too many stories in one time or ?
