This seems to be a common issue but I can't find a solution. There are no answers at the official adcenter forum.
I get the error "AdGroup ID is Invalid or Missing" every single time I've made a campaign in the desktop. This happens both when I import them (I have checked that the headers are correct) and make them from scratch in the desktop. If I d/l and work on a campaign that was built online then it works fine, but never if the campaign was created on the desktop.
Is there a fix for this? Can I ad a adgroup ID?
As it stands now the desktop is pretty much not usable.
