Hi! I understand you're having trouble with selecting your account in the Hubtel app on your iPhone running iOS 18.7, and previous attempts to fix it haven't worked. Let's get to the bottom of this together.

To start, could you tell me a bit more about what happens when you try to select your account? For example:
- Do you see an error message, or does nothing happen?
- Is the app logged in, or are you stuck at the login screen?
- Have you tried logging out and back in or restarting the app?

In the meantime, I can guide you through some steps that often resolve selection issues:

1. Restart the Hubtel App: Close the app completely by swiping it away from your recent apps, then open it again.

2. Check for App Updates: Go to the App Store and see if there's an update available for Hubtel. Running the latest version ensures you have all bug fixes.

3. Logout and Login: If you're logged in, try logging out of your account and then logging back in.

4. Clear Cache/Data: Although iOS apps don’t have a direct cache clear option, you can uninstall and reinstall the app. This can reset any corrupted data causing the issue.

5. Network Connection: Ensure your internet connection (Wi-Fi or cellular) is stable. Sometimes account selection doesn’t work if the app can't communicate with the server.

If these steps don’t work, there could be an issue with your account settings or a server-side problem. In that case, please confirm whether your account is fully set up and active on the Hubtel platform—sometimes account issues interfere with app features.

Would you like to try these steps now and let me know what happens? If the problem persists, I can help you take the next steps.
