Zwift Ride con KICKR CORE es compatible con TrainerDay Live
I am not sure if this is question or statement, but it should work fine.
I can confirm it works fine. Would be great to be able to pair to the Zwift Play shifters to change erg level/slope in Trainerday. I don’t think Zwift has released the info to do that so no one seems to be offering anything other than the QZ app available for iOS and Android.
