Maxwell's equations don't change if we replace time by its negative. This doesn't imply
retro-causality ; the speed of propagation is constant.

Maxwell's equations are incomplete without boundary conditions.
Causality is put in as a physical boundary condition in solving the wave equation.
Advanced solutions are also useful mathematically, but not as the physical result.
