Price by Formula Calculator for WooCommerce

Hello Dear Authorized

1- The plugin works for guest users. When a member is logged in, an empty table appears.

2- The product has been sent to the basket, when the shipping options are checked, the measurement unit does not work. The product unit price appears and the customer encounters the unit fee. Instead of 2700 euros, he pays 48 euros.

3- When adding formula product, we have options as product and category. Is it possible to display the formula for the hashtags determined by the update in this field? It would be perfect if it did.
Thank you for your attention.
