that sucks big time ☹️ and it's not fair at all! !!

Hi I just upgraded to privilege and should be able to read 7 extra chapters everyday, so I read till 200 yesterday, and today I should be allowed to read untill 207. but the chapter are still locked. I want to know why? I have paid to have the preview, but why has'nt the next 7 chapters unlocked for today. I feel like I'm being cheated by this app. while I enjoy the novel alot, even after paying to read for you it, it not allowing me😡
