newbie - Workflow only works for Owner - Admin account

I created several list workflows in o365 Nintex all are set to run when a new list item is created. New item is created via an InfoPath form. When I or a SP Admin create a new list item the workflow is initiated. When anyone else on the SP site creates a new list item the workflow does not initiate. Other users have Contribute permissions to the list. I also have a similar workflow that was migrated from on-site Nintex that works correctly (i.e. workflow is triggered when any user creates new list item. Anyone have any ideas how to correct?
