We’ld like to add videos to products gallery on woocommerce
1) Do you have any plugin recommendation?
2) I’ve reached to “Product Video for WooCommerce”. Do you have experience with this one with GP niche?
if thats the official one then there should be no problems with using that plugin with GP as GP uses the core Woocommerce templates.
However, for Niche, that uses a custom PHP element for the Stacked product images on Desktop view. That would have to be disabled for the video player to display. Can assist with disabling that if you need.
