That's correct. Unfortunately, your subscription expired in November of last year. Priority support, new software updates, and the use of Autotune are benefits of your subscription.

If you'd like to upgrade to the latest v4.3 release, or the upcoming v5.0 later this month, as well as continue using the Autotune configuration tool, you'd need to renew your subscription.

All the settings available in Autotune can be configured manually in the Facebook Developers area for your application. The only feature that you would be missing without an alternative is our Error Checker tool which scans for common conflicts in other extensions or configuration problems. We are constantly updating Autotune on our end, which is what your subscription helps to support.

Hope that helps explain, but if you have any other questions, just let us know.

Thanks,
Alex
