Yes. They seem to gate on a feature-by-feature basis, know when you bought the license, and you don't get access to the new features after 1 year (unless you're on their subscription plan). You do continue to get the latest app, which includes bug fixes, but the features released past expiration aren't available to you. https://dueapp.zendesk.com/hc/en-us/articles/360053244591-Wh...
