Troubleshooting

Working through BLE problems between the app and an Interlock — permissions, range, the advertising sleep, and connection drops.

When a QR or NFC scan fails — separating phone quirks from tag damage, and what to do at each branch.

When the gate kiosk misbehaves — pairing failures, codes that scan dead, locked or suspended kiosks, and connectivity.

The diagnostic path when a machine stays locked — from "is this actually correct?" through licence, connection, and device checks.

When pushes go quiet — permissions, battery optimisation, the delivery-health banner, and telling a muted type from a delivery fault.

Diagnosing sign-in failures on both surfaces — the wrong-app trap, SMS codes that never come, MFA lockouts, and corporate single sign-on.

When field records seem stuck — reading the sync state, pending vs failed, and the cases that genuinely need action.
