A. 1. Check your device storage: Ensure that you have enough free space on your device to save the exported video. Go to Settings > Storage to check available space. If it's low, delete unnecessary files or apps to free up space. 2. Restart the app: Close the Vont app completely and reopen it. This can help clear any temporary glitches that may be causing the export issue. 3. Update the app: Make sure you are using the latest version of Vont. Go to the Google Play Store, search for Vont, and check for updates. If an update is available, install it and try exporting again.

B. 4. Clear app cache: Go to Settings > Apps > Vont > Storage > Clear Cache. This can help resolve issues caused by corrupted cache data.
