Why does my add to cart button keep getting stuck on 'Adding...'?

I’m having trouble on my store. The add to card button gets stuck on ‘Adding…’ when pressed.

When opening the store on a new browser, the button does work once. But then when I try and add a different Item to the cart it just get’s stuck on ‘Adding…’.

When I click the button, I need to refresh the page before the item appears in the cart.

I also have trouble removing the item when it’s in the cart.

There’s a javascript error in a PageFly script. I would suggest reaching out to the app support to resolve.
