Hi! I understand you're having trouble downloading sounds in the iBird Pro app. I'd love to help you get that fixed.

To start with, could you tell me if the issue is that the sounds never begin downloading, or do they start but fail to complete? Also, are you connected to Wi-Fi or using mobile data? Knowing this will help me guide you precisely.

Meanwhile, here are some general steps we can try that usually fix this kind of sound download issue in iBird Pro on Windows devices:

1. Check Internet Connection: Ensure you have a stable internet connection. Sometimes sounds fail to download if the network is unstable.

2. Close and Restart the App: Fully close the iBird Pro app and reopen it. This can refresh background processes.

3. Clear App Cache: Sometimes cached data can get corrupted. You can clear the cache from the app settings or Windows app settings.

4. Check for App Updates: Make sure you are running the latest version of iBird Pro since sound download issues have been addressed in recent updates.

5. Reattempt Download: Try downloading the sounds again once you confirm the above.

If you have already tried these or the problem persists, let me know, and I can guide you toward more advanced options such as reinstalling the app or checking for permissions related to storage and downloads.

Could you please share what steps you’ve tried so far? That way, I can adjust my help accordingly.
