I have created a new site in our organization, I usually add Nintex Workflow and Nintex Forms when creating a site. In this case however the "Nintex Workflow" app is missing in the list of "Add an app", though upon checking the "Store", I can find the Nintex Workflow app.
My question is, why does the "Nintex Workflow" app suddenly disappears from the list when clicking the "Add an app".
Please heeelp!
