I downloaded the subscription key for an in-app purchase from Apple into a file named 'SubscriptionKey_5S5U32JN84.p8' However, when I try to upload this file I get this error: “Invalid file name, it should be SubscriptionKey_XXXXXXXXXX.p8. A file name with any other prefix could be a private key for a different Apple service. Please validate you are uploading a Subscription Key.“
I also tried renaming the file to ‘SubscriptionKey_XXXXXXXXXX.p8’ but got the same error.
What am I missing?
