When you set up a new widget, it is good to know that the video selection is not final, and you can always swap the video content whenever you prefer. Here's how: 👇
Step 1: Navigate to Publish → Select the Product Page/Other pages.
Step 2: Select the widget on the product details page and add videos.
Add one or multiple videos ➔ Click "Add Videos" button ➔ Select videos from your library.
Remove assigned videos from a widget ➔ Hover over the video ➔ Click the 🗑️ (Note: Content remains in the Library).
Change video order easily by dragging and dropping them.
The changes will come into effect immediately for the widgets that are already public and live on your site. You don't have to adjust anything in your store.
