I purchase this week and same issue. Been 2 days without a response and everytime I add info too my ticket to help with resolution they treat as new.
I used Woo’s Storefront Theme as just building an internal stores shop so wanted something light. Originally I thought the issue was with WPFront Role Editor as its a plugin that comes with WooCommerce & Storefront to manage Roles like Shop Manager. You need to have WPFront Pro version to manage order statuses. WPFront was hands on within a few hours of my ticket to them and proved it was issue with Order Status Manager.
Has anyone received a status or fix for this from WooCommerce?
