Q&A:
Q: Can I read deleted or recalled Whatsapp, BBM, Skype, Wechat or other chat/social app messages?
A: Because notifications were not saved by system anywhere, only after Notification History is enabled, these message can be read later.

Q: Why the app does not record any notifications?
A: There're 2 possible cause. #1. The accessibility service and Notification History Pro service was not enabled. #2. Other accessibility service are using the notification access. In this case, try to disable other services and have a try again. If still not working, please send me an email for further support.
