If you see certain product tabs greyed out for some (but not all) searches, it generally means that those greyed out products do not contain content for the searches you conducted.
When product tabs are consistently greyed out, it usually means your subscription does not include access to those specific products. Please check your overview page for a summary of the products included in your subscription.
If you wish to upgrade your subscription to include any or all additional products, please contact us at sustainablechemistry.support@enhesa.com.
