@AET720 I then began by using the iMessage App template in xCode. And BAM right off the bat, I could not get the In-App Purchases capability to show up when I select my iMessage extension target. When you add the In-App Purchase capability to a target in Xcode, it adds the com.apple.developer.storekit entitlement string. This entitlement isn't a supported entitlement as explained in Determining if an entitlement is real. For a list of entitlements Apple supports, see Capabilities overview > Supported capabilities. if you added the In-App Purchase capability to your app target in Xcode, remove it. It is unnecessary. This capability is already enabled when you use an explicit App ID. If your iMessage extension uses an App ID, In-App Purchase is already enabled.
