A. 1. Check your internet connection: Ensure that you have a stable WiFi or cellular data connection. You can do this by opening another app or website to see if it loads properly. If not, try resetting your router or switching to a different network. 2. Restart the app: Close the XDV app completely and then reopen it. This can help refresh the app and resolve minor glitches. 3. Update the app: Go to the App Store, search for XDV, and check if there is an update available. If so, download and install it as updates often fix bugs and improve performance.

B. 4. Clear app cache: Go to your iPhone settings, scroll down to XDV, and look for an option to clear cache or data. This can help resolve playback issues.
