Hello.

I have list workflows on several sites that trigger emails to one or two persons when item is created or changed. These have been working as expected since 2018. Yesterday, 4 different workflows on three different lists started sending 3-15 duplicates. When I check there is only one instance of the list workflow on the site, and the workflows only ran once for each list item.

We are still using Microsoft workflow cloud. 

Has anyone seen this or know what I can do to stop the duplicate emails? Tyia.
