Vipps generates order duplications

[kimhf]

When using the option to checkout with Vipps instead of the WooCommerce checkout, we occasionally end up with duplicate orders.

This issue has been reproduced in a test environment, where the payment app got stuck on the step to select shipping options (probably a separate issue), and the only option was to abort the payment. Then the initial order seems to have been canceled, and a duplication has been created.

Vipps seems to delete some of these order duplications, while others remain.

The expected behavior would be no order duplications.

Hello! Which version of the plugin? This should be fixed in the recent version, except in very rare cases. The solution may simply be to upgrade the plugin.

There is a support forum btw: https://wordpress.org/support/plugin/woo-vipps/

This is probably because Vipps Checkout, like Vipps Express Checkout needs to create the order before the user pays. Then, if they abandon the order (to modify the cart etc) we need to create a new one; the old order will be cancelled and later deleted, depending on your settings.

This is not easily fixable because of the constraints mentioned, though we do want to add mitigation measures for this as much as possible.
