Buy Me: Sticky Add To Cart Bar

I have been using the Buy Me Button via this app and noticed a glitch where it didn't update the cart drawer, only the floating cart button. I raised this with the developers on Monday afternoon and by Wednesday morning they had fixed the issue so that adding a product to cart via the Buy Me Button puts the product into both the floating cart button and the cart drawer. Great response from the team - speedy and fixed what I needed fixing.
