Hi there! I understand your MANGO app on your iPhone shows no data coming from the unit, and you've noticed the unit is operating with the wrong date. I'd like to get a clearer picture so I can help you better.

Could you tell me if the incorrect date is showing on the app itself or on the unit hardware? Also, is the unit connected properly to the network or app—like via Wi-Fi or cellular? Have you tried restarting the app or the unit? Any recent changes to your device or network?

Meanwhile, here’s a general step-by-step approach based on what you described:

1. Check Unit’s Date and Time Settings: Since the unit shows the wrong date, this could cause data synchronization issues. Many units have an internal clock that needs to be set correctly or synchronized with a time server. If you have access, try to manually correct the unit’s date/time or ensure it is set to sync automatically with a reliable time source.

2. Restart the Unit: Power cycle the unit by turning it off and back on. This often helps reset its internal clock and network connection.

3. Confirm Network Connectivity: Ensure the unit has proper network access. For MANGO apps and units to communicate properly, the required ports like HTTP (80) and HTTPS (443) must be open on your network. On your iPhone, check if the unit data source is reachable.

4. Restart the MANGO App: On your iPhone (iOS 18.5), fully close the MANGO app by swiping it away from the app switcher, then reopen it fresh to see if data loads.

5. Check for App Updates: Ensure your MANGO app is updated to the latest version via the App Store, as updates often fix bugs related to data syncing and display.

6. Verify iPhone Date & Time Settings: Sometimes, if your phone’s date/time is off or set to manual, that could interfere with syncing. Go to iPhone Settings > General > Date & Time, and set “Set Automatically” to on.

7. Re-Add or Refresh the Unit in the App: If possible, remove and then re-add or refresh the unit connection within the MANGO app’s device settings. This can re-establish syncing with correct timestamps.

If after all this the issue persists, we might need to look deeper into your unit’s internal logs or potential server-side syncing problems.

Does this make sense so far? Could you share more about your exact MANGO unit model or any error messages you see? That will help me tailor the steps further. Also, are you connected over Wi-Fi or cellular data on your iPhone when using the MANGO app?
