V2.1 camera no data received

I purchased :
Arducam 8MP Sony IMX219 Camera Module w/ CS lens 2718 (Raspberry Pi)

Product Code: RB-Adu-51

vcgencmd get_get_camera
Supported=1 detected=1

But raspistill says No data received from sensor.

The v2 has the sunny connector that is easily dislodged but I don’t see anything like that on this board.
