When i try to add Nintex workflow app to my share point could office 365 i get this "Sorry, this app is not supported on your server."
what I do as I called MS they said call Nintx?
Solved! Go to Solution.
It is possible to disable app add ins for a site collection or tenant. Do you believe that could be your issue?
You should be able to add the app regardless of having a subscription. You will have a trial window when added.
Are you able to create and run SharePoint designer workflows using the SharePoint 2013 Workflow Platform Type?
The reason I ask is that I have seen this issue before when the Workflow Manager was not enabled on the Tenant.
The above test will tell you if the Workflow Manager is working or not.
