A. 1. Close the app completely by double-tapping the home button (or swiping up from the bottom on newer iPhones) and swiping the HX hoverboard app off the screen. 2. Restart your iPhone to clear any temporary glitches. 3. Reopen the app and try streaming again. If the issue persists, check for any available updates for the app in the App Store and install them, as updates often fix bugs that cause freezing.
B. 1. Ensure that your iPhone has enough free storage space. Go to Settings > General > iPhone Storage and check the available space. If it's low, delete unnecessary apps or files. 2. Try switching to a different Wi-Fi network or using mobile data to see if the streaming performance improves.
