Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. For Apple Handoff and Continuity, first confirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled.
What this covers
- Apple Handoff and Continuity with this exact failure state
- Diagnosis across Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. Expected behavior: advertise eligible activity between nearby devices on the same account.
Isolate the component boundary
ReversibleConfirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled. Use a known reference input or manufacturer test and compare the result. Boundary to separate: Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support.
Correct only the proven cause
ReversibleUpdate, sign into the correct account or restart the one failed service. Correct the setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. Do not sign out of the account without synced data and credentials.

Common follow-ups
What should I check first when Apple Handoff and Continuity has this problem?+
Confirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled.
Why not factory-reset immediately?+
The useful boundary is Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not sign out of the account without synced data and credentials.
