aadnan181 , via OnePlus 6T , Apr 11, 2021 : Once in a while I get these blank notification sounds (notification sound with no actual notification). Very annoying as I have to check my phone just to see there's actually no notification. I checked the Notification settings and I noticed this "Enable Read mode notification for Manga rock". I uninstalled the app "Manga Rock" long time ago. Why's it still showing and that too in system's notification?!
