In Profile Merge Rules screen (Rule set as: - CAP + PMDG), can we see the authenticated IDs of users and device IDs (aam_uuid for browsers) stored in the Cross Dev data source? I am seeing a discrepancy in the UI - its a WordPress site which has only 4 registered users who can login (as seen in WP admin console), so it should be just 4 who have deterministically displayed their identity on web. Instead AAM UI shows 5, unsure how 1 additional to the count. Ditto for the Total Devices, i noted that i used browsers on laptop and smartphone to be 5, instead its showing as 7 in UI. Am i missing anything?
Also, I am just trying to read the authenticated activity trend chart should show count of people who have authenticated on a particular day, which means 3 people logged on 11 Aug, 4 on 12 Aug and 3 again on 13 Aug. If none logs in on a day, it should show 0. Right?
To answer your first question - you can export the cross-device data source used while creating the profile merge rule and see the ids. It's possible that since wordpress uses universal referencing methods, id sync code may be capturing admin login id as well.
Second, yes the authenticated activity trend chard would show the number of users authenticating per day.
