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...
That is so much more work than simply not getting the latest update. Imagine if sth like IntelliJ put everything behind feature gates instead of just telling you to download an older version…
