Zwift ERG and resistance not working with Kickr Bike shift

Hi Zwift,
I got a brand new Wahoo Kickr Bike shift to replace my other indoor trainer which i used mainly for Zwift. Since I been using my indoor trainer for years, the difference is even more apparent. Zwift resistance control to mimic terrain and slopes, and ERG mode for training plans is not working at all for my Kickr Bike. The resistance doesn’t change for anything. The bike only respond to gear shifting. My firmware version is 1.21.18 for Kickr Bike。 I tried using wahoo app and mywhoosh, the Kickr bike seems to be working well in those apps, responding as per expected. This probably means Zwift is not compatible or not working for Wahoo Kickr Bike?

Using same bike with same same firmware. All good in Zwift, no probleme at all. Tried both bluetooth and direct connection
