Thank you for your reply! We also had additional automations that probably won't work for the same reason:
https://prnt.sc/10kfvz1Automation :
Psauto.com.ua / Change order status
Psauto.com.ua / Remove deleted process products from an order on the website
Psauto.com.ua / Update the status of process products
You can check them too, and issue a total invoice to fix the current problem. Thanks a lot in advance!
