  1. investigating Sep 21, 2026, 05:18 PM UTC

    We are currently experiencing an issue where navigating a LIVE app incorrectly triggers the preview-loading experience instead of going straight to the live app, and that loading state can hang for 1+ minute, sometimes ending in an error. We are actively investigating and will provide updates as we learn more. We apologize for the inconvenience and appreciate your patience while we work on a fix.
