Debut theme buttons loading slow

[SKipp]

Buttons on the main page, product pages and checkout page are loading extremely slow in our shop https://vehicule-magazine.com

Losing lots of customers & Shopify customer support does not have an answer to this. Anyone here who has the same issue / a fix?

Example for a product: https://vehicule-magazine.com/collections/shop/products/cigarette-velvet-bomber-jacket

Add to cart button takes about 5sec to load (loaction Germany, tried every browser).
