A. 1. Check system requirements: Ensure your device meets the minimum requirements for running Reverb. This information can usually be found on the app's page in the App Store. 2. Update your iOS: Go to Settings > General > Software Update to check if your iPhone is running the latest version of iOS, as updates can improve compatibility with apps.

B. 3. Use an older version of the app: If your device cannot support the latest version, check if you can download an older version of Reverb that is compatible with your device.
