Previous versions opened the Scan Details if there was a detection (or file/s that couldn't be scanned). Why this isn't happening is beyond me.
Even more so as there didn't appear to be any notifications (a figure, 1, etc.) flagging. I would also have expected the tray icon to get flagged (Blue blob, if not serious) or ! exclamation mark (if more serious), since you didn't mention that, I can only presume you didn't have that.
