Upgraded to x20 pro plan, says im on free plan

Welcome to the community @owly! Is it still showing Free plan for you? In that case, have you tried logging out and back in, updating Codex, clearing cache or checking whether the subscription appears correctly on your account settings page? If the issue still appears to be that your account is showing the Free plan despite having paid for Pro x20, you may need to open a new support ticket specifically regarding the subscription status if you haven’t already.
