Whether you are an iOS developer testing a new subscription model or an everyday user trying to unlock a Pro feature in apps like Wanderlog, encountering an App Store error can be incredibly frustrating. One of the most common\u2014and perplexing\u2014StoreKit issues is Apple Error 21107<\/strong>.<\/p>\n

This specific code triggers the message: “There’s no information available for In-App Purchases. Try again later.”<\/em> It signifies a breakdown in communication between the app’s internal code and Apple’s App Store Connect servers. Let’s break down exactly why this happens and how to resolve it.<\/p>\n

<\/p>\n

\n

\u26a1<\/span> Quick Answer & TLDR<\/h2>\n

For App Users:<\/p>\n

    \n
  • The developer has misconfigured their StoreKit items or you are caught in a billing glitch.<\/li>\n
  • Fix:<\/strong> Delete the app, restart your iPhone, and reinstall it. If it fails, you must contact Apple Support directly to request a refund, as the app’s backend is broken.<\/li>\n<\/ul>\n

    For iOS Developers:<\/p>\n

      \n
    • Your App Store Connect product ID (SKU) doesn’t match your Xcode project exactly.<\/li>\n
    • Your “Paid Applications Agreement” in App Store Connect is missing or expired.<\/li>\n
    • You are attempting to test a Sandbox purchase using a standard, live Apple ID account instead of a Sandbox Tester account.<\/li>\n<\/ul>\n<\/section>\n

      What Causes Apple Error 21107?<\/h2>\n

      StoreKit Error 21107 (officially flagged as an invalid product identifier in Swift\/Objective-C) means Apple’s servers looked for the specific item you are trying to buy, but came up empty-handed. Because of Apple’s strict financial ecosystem, any slight discrepancy will block the transaction to protect consumer data.<\/p>\n

      \n\n\n\n\n\n\n\n\n
      Root Cause<\/th>\nResolution Strategy<\/th>\n<\/tr>\n<\/thead>\n
      Mismatched Product Identifiers<\/td>\nEnsure the string used in SKProductsRequest<\/code> matches App Store Connect exactly.<\/td>\n<\/tr>\n
      Missing Paid Apps Agreement<\/td>\nNavigate to Agreements, Tax, and Banking. Accept the latest Paid Applications terms.<\/td>\n<\/tr>\n
      In-App Purchase “Missing Metadata”<\/td>\nAdd a screenshot and proper description to the IAP product in Connect, then save.<\/td>\n<\/tr>\n
      Live Apple ID in Sandbox Mode<\/td>\nLog out of your personal Apple ID. Use a Sandbox Tester account created in Connect.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

      Developer Checklist to Fix the Error<\/h2>\n

      If you are coding an iOS app and are stuck hitting Error 21107 every time you fire your SKProductsRequest<\/code>, run through this strict diagnostic checklist:<\/p>\n

        \n
      • Check the SKU String:<\/strong> A single typo or misplaced capitalization in your Bundle ID or Product ID will trigger this. com.myapp.pro_yearly<\/code> is not the same as com.myapp.pro_Yearly<\/code>.<\/li>\n
      • Clear “Missing Metadata”:<\/strong> Look at your In-App Purchases tab in App Store Connect. If the status is “Missing Metadata,” Apple will not return product data to your app. Upload a 640×920 review screenshot to clear this status.<\/li>\n
      • Wait for Server Propagation:<\/strong> If you just created the In-App Purchase in Connect 5 minutes ago, be patient. Apple’s servers can sometimes take up to 24 hours to propagate new SKUs globally.<\/li>\n
      • Review Tax Documentation:<\/strong> The absolute most common hidden culprit is an unsigned tax document. If Apple cannot legally pay you, they instantly disable the StoreKit connection.<\/li>\n<\/ul>\n

        What to do if you are a User\/Customer?<\/h3>\n

        If you just downloaded an app, hit the “Start Free Trial” button, got charged, and then received Error 21107 when trying to unlock features, do not keep pressing purchase<\/strong>. The developer has broken their purchase configuration.<\/p>\n

        Since the app cannot communicate with Apple to verify your purchase, the “Restore Purchases” button will also fail. You need to visit reportaproblem.apple.com<\/a>, log in with your Apple ID, and request a refund stating: “In-App purchase failed to deliver due to developer Error 21107.”<\/em> Apple is well aware of this specific StoreKit error and routinely grants refunds for it.<\/p>\n
