Gravity Forms Address Enhanced v1.29.0 has been released. It fixes a bug with User Registration not saving subdivision codes sometimes.
Integration with the User Registration add-on allows for the subdivision (state / province / district) in an address to be saved as an ISO code, or a WooCommerce-compatible code so that address fields work properly on the WooCommerce checkout. When GF Address Enhanced was set to record the subdivision as a code instead of its name in Gravity Forms entries, the User Registration mapping was failing. Now fixed in this version.
You can update to the latest version from your WordPress plugin admin page. Here’s the full changelog for Gravity Forms Address Enhanced.
