New Grizl:OnFly. SRAM derailer doesn’t get power from the Bosch motor

Hey guys, just got my new grizl. Unfortunately after setting it up, looks like SRAM derailer doesn’t get power from the motor. I took the eTap battery from the dropper post, derailer booted up. I updated the firmware in the app. But when I insert the battery which is connected to the motor: nothing. Any advise?

Thanks
