I am getting the "Sorry, something went wrong" error when I separate conditions with an "and" or an "or" operations. This error occurs for any workflow actions with multiple conditions by "and" or "or" oparators.
This operation works perfectly if I only have one condition but returns an error if I combine multiple conditions.
You are right about both of the references.
With regards to the Nintex Workflow build, it would be Nintex Workflow 2013.
