Hi, We did.
We also changed the theme to 2020 to test if this is an issue with the theme or with the plugin.
In theme Twentytwenty all works. Including my other ticket about product images.
We checked all plugins and when YITH WooCommerce Product Add-ons & Extra Options Premium
is activated in woodmart the issue occurs.
But in 2020 theme with YITH WooCommerce Product Add-ons & Extra Options Premium
activated all works fine.
Please advise as this is an issue with theme I guess then.
