For the devs, just as a wishlist item:admin UI in Solr 9.10 should really have a "clear cache" button. After deleting a configset via the API, it still shows up in Cloud - Tree for some time and you can click on it (and files within) and get the NoNode exception from zookeeper.
It takes quite a few shift+reload's to update. It would be nice if it updated its caches on close+open the node, or had a "refresh" button.
I can make a Jira item for it, though it's a fairly minor thing. Dima
