Hi there! I understand you're not seeing the "Books" section in the EWA English Language Learning app on your iPhone. Let me help you with that.

First, could you tell me if you've recently updated the app to the latest version? Sometimes features can be moved or renamed in updates.

If your app is updated and you still don’t see the "Books" section, here are a few steps we can try:

1. Check Navigation Tabs: On the main screen or bottom menu of the app, look for sections such as “Courses,” “Library,” or “Lessons.” In some updates, the "Books" content might be integrated within these categories rather than a separate tab.

2. Account Level: The "Books" feature might be part of a premium subscription. Can you confirm if your account is the free version or premium? If free, some content like books might not be accessible.

3. Reinstall the App: Sometimes reinstalling can solve missing feature issues. To do this on iOS:
- Press and hold the EWA app icon.
- Tap “Remove App,” then confirm.
- Go to the App Store and download EWA again.
- Log in and check if the "Books" section appears.

4. Settings Check: Inside the app, go to your profile or settings menu and look if there are options to enable or show book content.

If none of these steps bring back the "Books" section, please let me know. We can then look deeper into account or app version specifics or contact the EWA support team directly.

Are you able to check these and tell me what you find? I’m here to help!
