Sessions and Users are visible in Adobe Analytics but not in AEP
I am working on a migration from Adobe Analytics to CJA, and current state both Adobe Analytics and CJA are running in parallel. Adobe Analytics is using the old client-side b/ss calls while CJA is pulling data from xdm interact calls.
When comparing data between Adobe and CJA, it has been observed that whole sessions attributed to one ECID are present in Adobe Analytics but not in CJA. There are page views and events that get collected in AA that aren't collected in CJA at all. The data collection is set up with the same rule triggers, it is not isolated to one browser/OS or anything like that. It is more like in some cases the entire interact call is failing while the AA beacon is sent without issue.
I am looking for insight as to why an interact call would fail when a b/ss call would succeed. It is not something I have been able to reproduce in browser so I am curious if there is a technical or latency difference between the two that would exist on an end user's browser that could be making the difference.
