After upgrading from XCode 7.x to 8.x, while submitting our app to the AppStore, we've encountered the following error:
Missing Push Notification Entitlement - Your app appears to register with the Apple Push Notification service, but the app signature's entitlements do not include the "aps-environment" entitlement. If your app uses the Apple Push Notification service, make sure your App ID is enabled for Push Notification in the Provisioning Portal, and resubmit after signing your app with a Distribution provisioning profile that includes the "aps-environment" entitlement.
Since nothing was changed in regards to our certificates and provisioning profile pairs, we were close to dismissing this as an Apple error.
