Refresh/rescan has no relevance to searching or downloading anything

If sonarr is not automatically grabbing episodes then assuming you did not disable RSS and are ignoring the resulting healthcheck or sonarr was unable to page back far enough due to your indexers having over 1000 results on ever RSS feed (they’ll be a warning entry in Events) then your indexers did not have a release matching your criteria for that series newly uploaded.

Sonarr never goes out and searches on its own - this is explained in the first FAQ entry
