Good Lord, not again. Guys, please read the other privilege threads and the explanations there before posting new complaints.
Again, buying 15 privilege chapters doesn't mean you get 15 new chapters. It means you get to stay 15 chapters ahead of non-privilege readers. No more, no less. So, for example, if you read until Chapter 1146, and you can't wait until tomorrow for Chapter 1147, you can buy the 5-privilege thing to stay 5 chapters ahead of everyone else who is non-privilege. That means you unlock until Chapter 1151. If you have cash to burn, or you're still too impatient to wait, you can then buy the 15-privilege thing to stay 15 chapters ahead of non-privilege readers - in other words, you unlock until Chapter 1161. You don't get 15 extra chapters. You stay 15 chapters ahead of others. I hope you guys understand the difference.
Of course there is no update once you purchase the 15-privilege thing - that is the highest tier. It's not as if the writer as a stockpile of 1,000 chapters somewhere for you to purchase over and over again. Chances are, she hasn't written Chapter 1162 yet, and will probably only upload it tomorrow. Your privilege allows you to be the first to read Chapter 1162, while non-privilege readers will only get to read a newly unlocked Chapter 1147. That's all. There is no point in trying to purchase privilege again - it's a monthly system that allows you to remain 15 chapters ahead of other readers, not give you 15 new chapters upon every purchase. So you have to wait 28 days for that monthly subscription to expire, and then renew it next month to stay 15 chapters ahead. Not buy 15 new chapters. It doesn't work that way.
There have been a lot of people explaining this over and over and over again, and honestly, could you guys just please read the explanations on the other threads instead of creating new ones or jumping into other existing ones and complaining about the same thing again?
