<!-- /section:pm-actions -->

<!-- section:outlook -->

- 🔴 The lack of updates for over 2,300 days indicates the app is in a terminal state, leading to inevitable obsolescence.
- 🔴 Broken support and registration flows prevent users from accessing content, which guarantees negative sentiment and churn.
