I installed the trial version of TaxJar for WooCommerce, but the tax calculations do not seem to work. Regardless of the zip code of the order, taxes come out to zero. Additionally, when you try to set the WooCommerce tax settings to Display Prices During Cart and Checkout = include, it reverts back to exclude. I even tried updating the db in wp_options, but it still reverts back. Is there a bug?
