Hi @thibotus01,
This is not a behavior we could observe anywhere else so far.
Are you seeing any similarities between affected orders? For example, are these all orders with only virtual products?
Could you please share with us your latest log files? Also, the PayPal MTS usually has a more detailed breakdown of which calls have been sent at which time if you can provide the respective debug IDs. It would be interesting to know whether the payment was captured right away or if maybe the capture called happened automatically shortly after the authorization as I’m not sure how this would look like in the log.
This shouldn’t happen, of course, so we’d be glad to look into this further, preferably if you could maybe send us your logs via private support ticket.
There is also a new pre-release version as the previous one had some compatibility issues with certain themes: https://github.com/woocommerce/woocommerce-paypal-payments/releases/tag/1.7.1-test2
Kind regards,
Niklas
