Hi @scriptgeni,
Sorry to hear the plugin does not work as you’d expected.
The attributes will always be displayed in the additional information tab.
What should be displayed in the new tab is the attribute description.
So one more factor is to ensure is the correct description source.
The default setting is “Use attribute tab description”, which is a new field introduced by the plugin on attributes. You can also switch to “Use WooCommerce term description” to use the default WC field.
The new tab will only be displayed, if at least one attribute has a description.
Let me know if you need further help.
Kind regards,
Mike
