I am using Strapi as CMS for a customer. In works collection, I set the option of “required field” to “title” (Type=TEXT) and “thumbnail” (Type=MEDIA).
When the customer publish the work without the field “title”, it works correctly and strapi does not allow to publish it. But when the field “title” is filled, but there is not a photo on “thumbnail” field, the customer can publish the work anyway.
