Unfortunately stores do not notify us or yourself when a release becomes available, it's just a case of checking the stores. Once your release has been approved, it will be available on most major stores within 7 - 14 days, however some stores can take up to 28 days. Please note that if you have set a sales start date on your release that is further ahead than this time frame, your release will become available... Source: over 1 year ago

Cool reader is also another option https://sourceforge.net/projects/crengine/. Source: about 3 years ago
