Hi everyone,

We've been experiencing an issue with the Qliro for WooCommerce plugin (by Krokedil) where orders paid with TWO Invoice randomly get put on hold with the error:

"Operation is not supported for this order. Another transaction is already in process. Please retry shortly."

Here's what we've done so far:

• Identified a race condition where payment_complete is triggered twice on the exact same second
• Contacted Krokedil who implemented an atomic lock fix
• Tested on staging + sandbox — worked perfectly
• Deployed to production — problem persists
• Disabled caching plugin (WP Super Cache) — problem still persists

The issue seems to be exclusive to TWO Invoice payments, never happens with other payment methods like Trustly or card.

Has anyone else experienced this? Did you find a solution?
