I have a freshly installed SP2016 farm with WFM installed. I'm facing this weird situation where when we try to create a List workflow, we would have missing SharePoint 2010 Workflow and a warning message saying "The option for the SharePoint 2010 Workflow platform is not available because the server administrator has disabled that type of workflow."
My research shows most people usually have problem with missing 2013 workflow because they do not have WFM installed. And research also shows that 2010 Workflow comes with Sharepoint 2013/2016 by default, but I could not find any place to enable the 2010 workflow. I've been researching for the whole weekend without luck...i'm hoping someone can shine some light on this issue for me, much appreciated!
