Check the task result, the product media in Shopify, and your theme settings.
Work through these checks in order.
- Task result: open the task in History. The product should appear in Processed Products & Results with a video player. If it is in the Error Log, no video was added
- Shopify processing: new videos can take a minute or two to process before they play
- Product media: click Edit in Shopify and look for the video in the Media section
- Position: if you chose Last position, the video may be at the end of a long gallery
- Theme: some themes hide videos in certain layouts or show only the first image on collection pages. Review the product media settings in the theme editor
- Cache: reload the storefront page in a private window
