Stripe Official - Express Checkout not working with discounted products

[Diwad]

Hi guys. 

Does anyone of you use official stripe module with express checkout on product page? It works fine when there is no discount. But when we use catalog price rules it doesn't work. Stripe prestashop support isn't really helpful. I assume some part pushes wrong prices when there is discount, but after 3 hours of searching I gave up. Maybe some of you had same issue and have a fix? 

With EUR when there is a discount it displays page with 1 eur to pay instead of the correct price. When we use our local currency it does not display the payment window at all.

Normal purchases through cart work just fine. I

I tried 3.6.1 version and previous ones.
