Narrative:
At preflight planning, we noticed write-ups that indicated that a hydraulic line was fixed previous night by mechanic. Write-up says hydraulic line not properly connected and it was fixed. We noticed it was same plane that we flew from ZZZ1-ZZZ on prior day flight. So we are writing this report because we apparently and unknowingly flew this airplane with an improperly connected hydraulic line because plane hadnT flown since we flew it into ZZZ. We don't know what hydraulic line it was but only that it was disconnected which was told to us by the mechanic that had fixed it as he was in operations prior to us taking flight.
