Hello @inpsydekrystian ,
I’m experiencing the same error on my ecommerce, using version 2.9.3, and we spent lot of time to investigate after a user reported it. Here the log, I cannot say if it is the main reason of the bug, anyway that’s what we think is the main possibility.
ERROR Order approve failed: Failed to create WooCommerce order: No shipping method has been selected.
I disabled all plugins, the error persists using Paypal with capture intent. It does work with authorize intent.
Have you had a chance to investigate the error further to get a fix?
I know there are so many variables and plugins on wordpress that make it really hard to keep everything in order, however it is quite critical that a crucial component like paypal integration is so unstable with each update.
Thank you for your support
Best regards
Alessio
