Hi @johnlim! We ended up getting back to you in a support request, but for anyone else experiencing this issue I’d encourage you to reference “The Airflow UI isn't updating after I deploy”.
We had one platform-wide incident 2 weeks ago that would’ve caused this behavior but that was thankfully temporary - typically, the Astro UI not updating is indicative of an underpowered Webserver (the Airflow component responsible for rendering the Airflow UI).
