Hey @TBZ! 
The subscription p8 key file is for non-introductory subscription offers and offer-codes so RevenueCat can securely authenticate and validate a subscription offer request with Apple. You can read more about this in our iOS Subscription Offers doc: https://docs.revenuecat.com/docs/ios-subscription-offers
I see the description for redeeming Offer Codes from the app with presentCodeRedemptionSheet().
But, if we have not implemented that in app, and a user redeems via App Store directly, will RevenueCat pick it up (entitlement.isActive)?
i.e. What is required to recognize in appthat a user has redeemed an Offer Code via App Store?
thanks
I can confirm that you can send out Offer Codes for your app, using URL for redemption, with no extra coding or setup.
e.g. emailing a link for ‘1-month free’ for new user installs
@cody I can’t find in the docs how I can upload a p8 file for testing using the storekit config file. When I try to pull the SKPaymentDiscount, I get an error that directs me to this url https://docs.revenuecat.com/docs/ios-subscription-offers , but these aren’t for .storekit sandbox testing.
