A. 1. Ensure that your iPhone is running the latest version of iOS. Go to 'Settings' > 'General' > 'Software Update'. 2. Clear the app's cache by going to 'Settings' > 'Hume Health' and selecting 'Clear Cache' if available. 3. Restart your iPhone to free up memory and resources. 4. If the app continues to crash, consider uninstalling and reinstalling it to reset any corrupted files.

B. 1. Check if there are any pending updates for the Hume Health app in the App Store. 2. If the app is updated and still crashes, try using the app in a different network environment (Wi-Fi vs. cellular) to see if connectivity issues are causing the crashes.
