Bad form not sending out an announcement via email or putting a banner in the app announcing the change. If I hadn’t gone to check on my subscription, I wouldn’t have known it wouldn’t be renewed.
Suggestion 1 - Give us the option to pay for all chapters of the book all at once. Not just the translated, but all the chapters to come as well. The price for the entire title shouldn’t be higher than print version of the book since it’s ebook.
Suggestion 2 - Tiered subscriptions as mentioned above.
Suggestion 3 - Lower the chapter SS costs (no more than 5 SS per chapter) or give us more SS for our money (5000 SS for $5). No ONE book should cost $70-$200 to read. For titles with over one thousand chapters, their readership will tank if you go pure SS without dropping costs of SS and the cost of chapters.
