I am having the same problem a pop up comes and it gets stuck so cannot add any employee info its strange though I use multiple EINs in other companies which were set up before DD no issue only in the new company set up this is happening been 2 wks now have talked to at least 4 people in the desktop payroll support no help somebody from outsource talks for hrs does exactly the same steps which the previous person has done and finally give and blame it on the engineering team they are working on it that's what they !!

Not sure how this will be resolved if not maybe I need to use payroll via another company
