Hello friends, 

I'm getting quantity selector issue in my shopify store, when I try add more than one products or minus so the +, - is not working but when I manually write 1, 2, 3 in box and added to cart it's working. 

This issue is on products and cart page. When I inspect so this is what I am getting, 

timber.js:91 Uncaught ReferenceError: Currency is not defined
at updatePricingQty (timber.js:91:3)
at HTMLButtonElement.<anonymous> (ajax-cart.js:504:11)
at HTMLButtonElement.dispatch (jquery-3.5.0.min.js?v=16874778797910128561693478356:2:42571)
at v.handle (jquery-3.5.0.min.js?v=16874778797910128561693478356:2:40572)

Anyone can help me please?
