We are seeing intermittent issues where preview builds and redeploys are not being triggered automatically. This has been traced to an ongoing GitHub webhooks degradation that is affecting a subset of webhook deliveries.

While this issue persists, some documentation changes from commits or pull requests may not deploy automatically. Customers can trigger a manual redeploy to publish updates, or contact support for assistance.
