Hi there! I understand you’re having trouble with the Merlin Bird ID iOS app freezing when you try to add a new region. To make sure I give you the best guidance, can you tell me a bit more? For example:
- Which version of iOS and the Merlin app are you using?
- Have you tried restarting the app or your device since this started happening?
- Are you connected to a stable internet connection when trying to add the region?

This info will help me tailor the solution better.

Meanwhile, here are some general steps that have helped others with similar issues:

1. Force close and restart the app: Double-click the home button or swipe up (depending on your iPhone model), then swipe the Merlin app off the screen to close it completely, and open it again.

2. Check your internet connection: Make sure you have a stable Wi-Fi or cellular connection, as downloading new regions requires internet.

3. Restart your device: Sometimes a simple reboot can clear up temporary glitches.

4. Update the app: Ensure you have the latest version of Merlin Bird ID installed, as previous versions have had bugs causing freezes when selecting regions.

5. Clear app cache/data (if possible): Although iOS apps do not usually allow manual cache clearing, you can try uninstalling and reinstalling the app. Just make sure you’ve backed up any important data or saved sightings.

If these don’t help and you’re on iOS 18 or later, some users have reported the app freezing due to a bug introduced in recent updates. The developers might be working on a fix, so keeping your app updated is important1.

If you’ve already tried these or have more details, please let me know, and I’ll guide you through more specific troubleshooting or alternatives! Are you comfortable trying these steps now?
