I am facing the issue on the checkout page. If customer click on the place order button multiple time then multiple order will be placed with the same quote id.
I am using Amasty One step checkout extension and this issue only happens if I enable this extension.
This issue produce in the Magento cloud (My staging and integration environment) only. The same code working fine in my local and dev environment.
- Disabled class applying when I click on the place order button.
- Magento 2 Duplicate Orders I have created this module also to prevent duplicate order. But it did not work.
Please help me. Your help would be appreciated.
