So here's the scenario, I've been being notifed with manga/manhwa updates every morning and night and not in betweens. Like I see the latest updates corner and there'd be tons of updates for the manga or manhwa that I've been reading but the notification won't ring up any updates until it gets at night or when its morning and nowhere near outside that timeframe unlike before. Is it the new standard timeframe for being notified? I'm confused
