Hi there! I understand the Select button in your Agnihotra Buddy app is not working. To help you better, could you tell me a bit more? For example:

- When exactly does the Select button not work? (e.g., right after opening the app, when you try to choose timing or location)
- Does pressing the button show any response, or is it completely unresponsive?
- Have you tried any steps already like restarting the app or your device?

Knowing this will help me guide you through the best troubleshooting steps! Meanwhile, I’ll start with some basic checks we can try.

1. Restart the Agnihotra Buddy app completely. Close it from your recent apps and reopen it.
2. Restart your Android device to clear any temporary glitches.
3. Ensure the app has all required permissions, especially location access since it uses sunrise/sunset timings. You can check this in your device's Settings -> Apps -> Agnihotra Buddy -> Permissions.
4. Check if your device's date and time settings are set to automatic for accurate app functionality.

If these steps still don’t make the Select button work, I can help with a deeper dive such as clearing app cache or reinstalling the app. Let me know how it goes or if you have tried some steps already!
