I think you have a bug in your theme because i can’t see image of category if i share a category url for example in whatsapp. I only can do it if i set a image in yoast seo. But products work fine, it is only happening in woocommerce categories. You can try in url i share in private. Please see my video too. Thanks.
The theme doesn’t have built in functionality for setting which image is to be used on social media platforms, you would have to use a plugin like you mentioned.
Yes, i am using yoast seo but it doesn’t work
In products it works fine, but not in category.
Could you tell me how can i do it?
If you edit a category, then you will see options to set social media images at the bottom of the page. If that doesn’t work on Whatsapp, then you would have to reach out to Yoast or Whatapp support to try to find out what is required for that particular platform.
