Hello! It sounds like you're experiencing an issue with TFRs not displaying in your Stratus Insight EFB app version 6.2.0. Let's work through this together!

To start, can you please confirm if this problem happens consistently or if it occurs only under certain conditions? For example, is it after updating the app, or has it always been that way? Additionally, are you connected to a Stratus receiver via Wi-Fi when trying to view the TFRs?

Here are a few steps we can try:

1. Check Your Wi-Fi Connection: Make sure that your iPhone is still connected to the Stratus receiver via Wi-Fi. Sometimes, if the connection drops, the app may not display the latest TFRs.

2. App Permissions: Ensure that the app has the necessary permissions enabled. Go to your iPhone's Settings > Privacy > Location Services, then make sure Stratus Insight EFB is set to "While Using the App." This allows the app to retrieve location-based data like TFRs.

3. Restart the App: Close the Stratus Insight EFB app completely and then reopen it. This can refresh the app’s connection to the TFR database.

4. Reinstall the App: If the TFRs still don’t appear, consider deleting the app from your device and reinstalling it from the App Store. This may resolve any lingering issues from the previous version. Make sure to back up any necessary data before doing this.

5. Check for Updates: Confirm that you're running the latest version of the app. Sometimes, newer updates fix bugs related to data display.

If you've gone through these steps and the issue persists, I can assist you in reaching out to higher-level support for further help. Please let me know how it goes!
