Common issues

Missing fonts or shifted layout

The presentation may not display correctly if the device lacks the original fonts.

  1. Install the missing fonts on your device.
  2. Embed fonts when saving the presentation in PowerPoint.
  3. Export the presentation as a PDF to maintain layout integrity.

Embedded videos not playing

This can occur if the video codecs are not supported on the device.

  1. Re-encode videos to a widely supported format like MP4 with H.264 codec.
  2. Ensure all media files are properly linked and accessible.

Security note

Be cautious when enabling macros in presentations from unknown sources.
