A. 1. Force Close the App: Double-tap the home button or swipe up from the bottom of the screen (for iPhones without a home button) to view open apps. Swipe up on Chirp Audiobooks to close it, then reopen it. 2. Check for iOS Updates: Go to Settings > General > Software Update to ensure your iPhone is running the latest version of iOS, as updates can fix compatibility issues.

B. 3. Free Up Storage: Go to Settings > General > iPhone Storage and check if you have enough free space. If storage is low, delete unused apps or files.
