Body Battery on 3rd party watch faces

so, i'm guessing this is due to Garmin's neglect of updating our firmware, but i'm hoping that someone else can try this out. 

it seems CIQ developers can now put Body Battery on their watch faces for the newer System 5.0 watches like ours. yet, when i install the following watch face, i get n/a for the body battery field. i've written the developer but not response yet...

anyone try this out yet?
