Wrong stock quantity of products in concurrent orders

Hi there,

Thanks for that video – that helps to illustrate things in awesome detail.

In order to troubleshoot this further, please do the following:

• Share a copy of your system status report as found under **WooCommerce > System Status**
• Share a screenshot of how that product is configured, specifically the “inventory” tab as found under Products > All Products > YOUR PRODUCT > Product Data > Inventory

Thanks!

thanks for reply,

Thanks for that system status report – while it is a pretty clean site, it also indicates that this isn’t something that we can test from our side as the site isn’t publicly available at the moment.

If you have that site loaded to a publicly available domain and you’re still getting the same thing, please let us know and we’d be happy to take a closer look ??

Hi @mostafa793,

It’s been a while since we heard from you, so I’m marking this thread resolved. Hopefully, you’ve been able to resolve this, but if you haven’t, please let open up a new topic and we’ll be happy to help out ??
