ChainDynamics from Control Rig not playing secondary motion in Sequencer

Hello
I’m new in Control Rig. I create the simple chain by ChainDynamics component from 2 bones and 1 controller on the end of the chain. It’s all connected to the head. When I rotate the character head in the editor I have a nice secondary motion. But when I do the same thing in the Sequencer I have no effect of secondary motion.
What I’m doing wrong? Is there any switch on character mesh setup that I miss? Or I should add something on the Backwards Solve?
