Ajax Add to Cart Performance issue

Hello, I faced a problem with very slow response from Ajax Add to Cart on Shop and Single Product pages. After long time debugging, it turns out that your plugin is causing this issue. More precisely, kp_is_checkout_page() function is taking extra 1,5-2 seconds for processing, which is called by woocommerce_after_calculate_totals action – https://plugins.trac.www.ads-software.com/browser/klarna-payments-for-woocommerce/trunk/classes/class-kp-session.php#L57.

I was able to solve this problem by replacing the conditions kp_is_checkout_page() and kp_is_available() in line 66 – https://plugins.trac.www.ads-software.com/browser/klarna-payments-for-woocommerce/trunk/classes/class-kp-session.php#L66.

Current version:

if ( ! kp_is_available() || ! kp_is_checkout_page() && ! KP_Subscription::is_change_payment_method() ) {

Fix version:

if ( ! kp_is_checkout_page() || ! kp_is_available() && ! KP_Subscription::is_change_payment_method() ) {

So now kp_is_available() function is calling only on Checkout page and not loading Add to Cart feature. Please implement these changes to your next update as it’s very important to have faster performance.

I hope this issue will be resolved for all users of your plugin.
