aps-environment is 'development', indicating a non-release build configuration shipped to users.
How it's exploited
aps-environment=development points pushes at Apple's sandbox gateway. Production devices simply stop receiving pushes, and the mismatch signals a mis-signed build.
Why it matters
Broken push notifications for real users and a hint the whole signing pipeline used the wrong profile.
How to fix it
Re-sign with a distribution provisioning profile so the entitlement becomes production.
