Our iOS app fails to install via Ad Hoc or Development distribution with error: 0xe8008018 (The identity used to sign the executable is no longer valid). Environment: macOS 15.6.1, Xcode 16.0 Team ID: 8CJTVD465A Tested on iPhone 8 (iOS 16.7 + iOS 16.2) What works: TestFlight ✅, App Store ✅ What fails: Ad Hoc ❌, Development ❌ Key evidence: OCSP returns "good" for all certificates Brand new certificate (created today) → same error Install succeeds in Airplane mode but app shows "not available" at launch 4 different certificates, 3 profiles, 2 Xcode versions, 2 devices → all fail codesign --verify passes locally Full cert chain verified: Leaf → WWDR G3 → Apple Root CA This indicates Apple's online verification service is rejecting our team's signatures. Has anyone seen this or know how to resolve?
