A. 1. Check text settings: Before exporting, ensure that the text boxes are properly set up and not hidden or off-screen. Adjust their positions if necessary. 2. Export in different formats: Try exporting the video in different formats or resolutions to see if the issue persists across all options.

B. 3. Re-add text after export: If the text disappears, consider adding it back in a video editing app after exporting.
