If you want to show only one product on all videos inside the widget, instead of adding this product to all videos manually, you can use the new feature.
This feature will work only in the fullscreen player and with the following widgets:
Carousel with videos
Stories with videos
Spotlight
Find the widget you want to update
On the right sidebar, find a block and click on the “Override product for all content” checkbox.
Click on the “Select product” button and find the product you want to attach.
Save the changes
Customers will see only selected products, even if some videos have different products.
