Environment - SharePoint Online
Apps - Nintex Forms & Workflow Loaded
Issue - After months of having Nintex Forms and Workflow on a site, I have logged on this morning to find the Nintex Form Icon missing from the List Tab ribbon. The Nintex Worklow Icon is still there and the Nintex forms previosuly created against SharePoint Lists on the site are also still there.
I have trusted the App in the App Permissions area but still no Icon on the ribbon.
