Troubleshooting your display
Check where readings stop: the source app, sharing service, or display.
Glucose Display is a secondary display. Follow your CGM manufacturer’s instructions and use your primary CGM app/device for treatment decisions and primary alerts.
No data
- Check the newest reading and timestamp in the primary CGM app.
- Check sharing is enabled and the follower connection or Nightscout uploader is working.
- Check the display is connected to Wi-Fi with internet access.
- Review the setup for your provider.
Delayed readings
Compare timestamps in the source app, sharing service and display. Check source internet access and background-data permissions. Try a trusted alternative network to isolate Wi-Fi restrictions. Missing history is not guaranteed to backfill.
Login rejected
- Dexcom: use the wearer’s account, matching region and Phone or Email/Username option.
- Libre: use the receiving LibreLinkUp follower account and matching region; confirm the invitation is accepted.
- Nightscout: use the base URL and separate credential field; check the exact error.
School, work or hotel Wi-Fi
Restricted networks can block access. Try a trusted personal hotspot to isolate the problem. If the display reports a limited connection, Network Status offers Connect to WiFi Network and Complete WiFi Sign-In. Some sign-in networks may still be incompatible; opening the settings does not confirm a successful connection.
Clock or reading time is wrong
For the device clock, open Settings → TimeZone → Adjust Time Zone and check Android’s time-zone setting. If that screen is blocked, tell support your app version and what appears.
A reading-time offset is different from stale data. Compare the source timestamp before changing Settings → DATA → Reading Time Correction; contact support if unsure.
Still stuck?
Contact support with your source, country/region, app version, exact error, phone OS and network type. A screenshot with personal details hidden can help. Do not send passwords, access tokens or API secrets.
