Afterpay On‑Site Messaging

The messaging is just that, a message, it shows customers on the product page and the checkout page that its available, the after pay button turns up after they click checkout on my shopify store. If you click on the green messaging button it just gives the shopper the run down, it doesn't take them to pay via after pay. So i followed the video and it showed up straight away. The reviews really freaked me out I didn't know what was going on!
It works anyway so nothing to complain about from me..
