Hello,
I added the dynamic button on my product page, but I would like to change the position.
Here, the dynamic button is to the right of the purchase button. I’d like to put it below. 
Now :
What I would like :
My theme is Broadcast.
My website is : www.hedisonparis.com (no pass word)
Thank you so much for your help !
