Hi there! It sounds like you're experiencing an issue with the Merlin Bird ID app changing languages unexpectedly. That can be confusing for sure.

To help you better, could you let me know if this happened after a specific action, like an update or adjusting any settings? Or has it been happening intermittently?

Generally, the app can change languages due to a few reasons:

1. Automatic Language Settings: The app might automatically detect the language based on the settings of your device or app preferences.

2. Accidental Changes: It’s possible to accidentally change the language within the app’s settings.

3. App Updates: Sometimes, an update might reset some of the preferences back to default.

If you're looking to set the language back to your preferred choice, here's a step-by-step guide:

1. Open the Merlin Bird ID app.
2. Look for a settings or preferences icon (usually represented by a gear icon).
3. In the settings menu, look for an option labeled "Language" or "App Language."
4. Select your desired language from the list and save the changes.

If you have deeper issues or the option is not visible, I can check for more detailed guidance. Just let me know!

Are you satisfied with the solution I provided?
