The entry door bows outward 1/8" or so at the center near the latch. It closes OK if pressure is applied on the latch where the handle is. The bow is gradual but is easily detected as the door is almost closed. Is this regularly seen or at least can it be "bent" back to being straight? The door cannot be closed by gently giving it a shove.
Outside door or screendoor?
I had the same problem with my screened door. Dealer was able to bend it back into shape.
My outer door was tight closing at the latch until I adjusted the door stop.
