Billing Grace Period is Apple’s new feature. With Billing Grace Period turned on, Apple extends subscription for additional 16 days (or 6 days in case of weekly period). During grace period developer must grant premium access to subscriber. Once Apphud detects grace period, user's subscription goes to Grace state, and Apphud SDK isActive()
method will return true
. Existing billing cycle will not break, which means days within grace period will count as paid days. After grace period is over, if subscription wasn't recovered it will go to Expired state. Apple will still attempt to recover subscription within up to 60 days unless manually canceled by user.
