Hi All,

We have an application that is running NOP Commerce 3.8 and we have deployed the application to an Azure Web App.

The application ran fine under single instance and everything worked as expected but when we tried to run under two Web App Instances to spread the load and offer some resilience we noticed that the NOP Scheduled Tasks ie: (Send Email) were triggered more than once which resulted in customers receiving duplicated emails.

This seems to be related with the fact that the operation was performed by both instances at the same time.

Does anyone have any advice how to fix this?
