回复 Quinn - Apple Developer Forums Thanks Quinn! You're absolutely right — I confused the certificate identifier with the Team ID. My actual Team ID is CK4269T4Q4. So to restate the real issue: I'm unable to run my development app on my iPhone (iOS 18.7.9). Every time I try, I get: "The Developer App Certificate is not trusted." The strange part is that Settings → General → VPN & Device Management is completely empty on my iPhone — there's nothing to trust. I've already tried: Deleting all certificates/profiles and starting fresh Resetting all iPhone settings Toggling Developer Mode on/off + restarting Installing intermediate certificates (G3/G4) Re-signing with --timestamp=none Nothing has made the "VPN & Device Management" section appear. Could this be a known issue with iOS 18.7.9? Any suggestions would be greatly appreciated.
