Apple gave us a little surprise yesterday without telling us. There is a new entitlement that is added when you regenerate your distribution certificate. When you regenerate, as others said, it should fix your problem. It's not due to magic though, it's because the missing entitlement is now there beta-reports-active = 1

Once you download your new provisioning profile, make sure the entitlement is there, rebuild your IPA and this warning should finally go away. If you manage your own Entitlements.plist be sure to include this new key.
