A. 1. Ensure that your iPhone is running the latest version of iOS. Go to Settings > General > Software Update and install any available updates. 2. Check your internet connection. A weak or unstable connection can cause the app to crash during uploads. Try switching between Wi-Fi and cellular data to see if the issue persists. 3. Clear the app's cache by deleting and reinstalling the app. This can help resolve any corrupted data that may be causing the crashes. 4. If the problem continues, try uploading smaller files to see if the app can handle them without crashing.
