Hi Everybody!In the office, we have been trying to see which devices
opened specific campaigns..if we only use device dimension with the open
metric, we can get it for all the campaigns ever released.. But how can
I do that for specific ones? For instance, in the image above I´m
filtering the delivery for specific campaigns (for example the fall
ones).. and I want to see the devices for them. But I want to see the
total devices open for these 4 campaigns as in a sum, and right now I
can only see...
