I've integrated Stripe (its official module, latest version 2.1.4) as payment method along One Step Checkout from Amasty in Magento 2.3.5.
Something seems wrong as "Place order" button is not working. "Place order" button is clickable, but nothing happens. When I select another payment method, it works fine. But selecting "Stripe" as payment method it don't.
If I disable One Step Checkout, it also works fine (including Stripe).
So the problem is between Stripe module and One Step Checkout from Amasty. Any thoughts on this?
