# Common Issues and Solutions

1. ### Webpage Crashing

Issue: The visualization or dashboard page may crash or freeze after being open for a while.\
Solution: Refresh the browser page. If problem persist, please contact us indicating URL and how to reproduce the crash.

2. ### Boat Unable to Connect

Issue: A boat cannot connect or appear in the tracking session.\
Solution: Make sure the device has a stable internet connection and that tracking is activated. If the issue persists, please report it including the race name, boat name and time.

3. ### Tracking Not Stopping Automatically

Issue: A boat keeps transmitting data after the race ends.\
Solution: The Termination Area only takes effect once the boat has crossed the start line. Make sure the session has a configured start time to activate this feature.

4. ### Missing Data in Replays (Distance or Position)

Issue: Replays don’t show boat positions or distances between boats.\
Solution: For real-time classification and boat distance to work, the following must be set:

* A valid course
* A defined start time
* At least one wind data entry

5. ### Insights Not Working

Issue: The Insights section fails to load or shows incomplete data.\
Solution: Make sure all location data points are present. Gaps in recorded location or incorrect mark setups can break Insights. Review your course and mark configurations.

6. ### SMS Notification Failures

Issue: SMS messages are not delivered.\
Solution: We might have to allow your country prefix. Contact us with the phone number and message details.

7. ### App Compatibility on macOS

Issue: The mobile app doesn’t work on certain macOS versions.\
Solution: Ensure your system is running macOS 12.0 or later for full compatibility with the latest version of the eStela app.

8. ### Transferring an Account to a New Email

Issue: A user wants to move their account to a different email.\
Solution: Contact support with the current email and the new email. We’ll handle the transfer, and you may be asked to reset your password afterwards.

9. ### Problems Importing Boats

Issue: Some boats aren’t imported correctly or receive a new access code.\
Solution: Only boats that have participated in a tracking session will retain their original access key. Inactive boats may need to be manually imported—contact support for assistance.
