When using power match, do both the trainer and the PM need to be calibrated?

I am using P1 pedals and a Wahoo Kickr. Before each session, do both power meters need to be calibrated? does it matter in which order they are calibrated?

As a (perhaps) secondary matter, for the P1 pedals (or any pther PM for that matter) is there a material difference between using the TR app to calibrate vs the device’s own app?

Thanks,

Hy
