Test HTTPS and push separately. Receipts stay on this device, even offline.
*Device receipt time minus sender time; clock skew and OS scheduling can affect this. HTTPS reachability is measured only to this app’s server, not the whole internet.

2. Schedule a flight
Save this while online. The ground server sends automatically, even when this app cannot reach it. Notifications update one visible card.
No schedule saved on this device.
3. Record conditions
Turn on airplane mode, then re-enable Wi-Fi. Label the onboard service so full-access flights remain useful baselines. Labels and notes work offline.
Export works offline. When online it includes the server’s send log. An accepted send means the push provider accepted it—not that your device received it. No receipt is inconclusive until send logs are reconciled.
