I am working on migrating the nintex workflow from on-premise to o365.

Facing an issue mapping the common varibles which are available in on-premise such as workflow start date etc. under common tab.

In office 365 not seeing common tab/ variables which are listed under common tab of on-prem workflows. 

Please suggest, Am I missing somethings? from where we can access all those in office 365?

Thanks in advance!
