We didn't check the igniter, though it sounds okay--and she
had no trouble with the grill last time she used it. I'm wondering if
maybe the move loosened something(s).

Possible. It may have turned away from the point of the arc and is not
sparking. Look to see if it is.

Since you do not smell gas, it is possible that the OPD valve got jostled in
transit if the tank was laid down. That would block the gas flow if it
stuck. Did you try the spare tank?
