Kickr Snap "control w/ Ant+ Power Meter" enabled---still need to calibrate?

Actually I’ve been having a ton of issues with TrainerRoad and I’ve been working with support for a month now. Tons and tons of issues. I wanted to try pairing the PM with power match on the Kickr then pair the Kickr with laptop/TR using only Bluetooth. Someone told me on this post it’s possible but I also have to pair PM to TR for cadence.
