Hi, everyone.
In the Profiles Overview, you can see the count of profiles with a certain identity. However, when I use the audience builder to set that identifier to exist (for example, ECID exists), the count is much different (larger for some identifiers and smaller for others). My understanding is that the audience builder works on the profile level, so I don't understand why there would be a mismatch. To be clear, even with the error bounds for the estimator, there is still a major difference.
ECID in profile overview: 109M
ECID in audience builder: 91M
Has anyone else experienced this or know why this could be?
Thanks,
Kendall
