When I click on the Nintex Worklow button in my List or Library ribbon, nothing happens.
In O365, I have removed the Nintex Workflow app and install it again. Still the same issue.
When I am trying to install it from a site in the same tenant on which I never install it, I get the error 'An unxpected error occurs'
Nintex Forms is OK.
Any idea to solve this issue?
Thanks for your help,
