A. 1. Clear the app's cache by going to Settings > General > iPhone Storage, selecting the HX hoverboard app, and choosing 'Offload App'. This will remove the app but keep its documents and data. Reinstall the app from the App Store. 2. Ensure your internet connection is stable. Test your Wi-Fi speed using a speed test app and consider resetting your router if speeds are low.
B. 1. Disable any background app refresh for the HX hoverboard app by going to Settings > General > Background App Refresh and turning it off for this app. This can help improve loading times. 2. Restart your iPhone to refresh the system and potentially speed up app loading.
