The flow approval "Sent" history is in Chronological order (i.e. oldest first) where as all other views are reverse chronological order (i.e. newest first). I would expect that the "Sent" view would align with the other views e.g. "Received". This becomes an issue if you have lots of "Sent" approvals, which requires the user to scroll and click "Show more" to see their most recently sent approval tasks.
