I was looking at this thread (How to refresh dungeon.streamlit.app page preview?) and it appears that once the initial share preview has been generated, it can take multiple days for it to refresh. However, the official docs say it should only take up to 24 hours: Share previews - Streamlit Docs.
I created an app and initially had it set to private, at which point the share preview displayed a “Not found” preview. Even after changing it to public visibility, the share preview hasn’t changed in the last day. Is there a way to force it to re-crawl/update?
