PayPal doesn't clear Minicart but cart

[grasdaggel]

We have found a weird bug. If a customer is paying with PayPal the Minicart doesn't get cleared. However, the cart is empty, so if you click "go to cart" you see "there are no products in your cart".

Bug only occours when using PayPal out of sandbox mode.

How can we fix this? I was thinking about a session destroyer on the success.phtml but wasn't lucky to find a solution for this.

Any ideas? Its kinda important for us.

We are using:
PHP7
Magento 2.0.4

Since such blocks like Minicart are rendered on client side based on data stored in local storage, the fix is basically to specify actions which must invalidate particular sections of customer data: https://github.com/magento/magento2/blob/develop/app/code/Magento/Paypal/etc/frontend/sections.xml

So, probably some other actions than "paypal/express/placeOrder" and "paypal/payflowexpress/placeOrder" are involved when you are out of sandbox? I'm not sure such scenarios are frequently tested by the way.

Can you elaborate how to apply a fix here? Not sure if I want to change PayPal-core-files. :/

Look into Network tab of Developer Tools during your scenario and note actions involved in the process.

If there are some missing in section invalidation config, add them similar to:

<action name="paypal/express/placeOrder">
        <section name="cart"/>
        <section name="checkout-data"/>
    </action>

This issue is already fixed in develop branch, closing the issue.
