I'm trying to test in-app purchases in my app in the sandbox environment. I've purchased a one-time purchase in the app, but no purchases are visible under "Manage Transactions..." in Xcode. Deleting the app from the device as well as deleting the directories ~/Library/Caches/com.apple.appstoreagent and ~/Library/Caches/com.apple.storekitagent does not remove the purchase from the app. This makes it impossible to fully test purchases in the app.
