I am seeing Enrichment occurring. When the page loads and I run "utag.data" in the console, the UDO will appear. Expand the results and scroll to the bottom of the list and you'll see several "va.attributeType.attributeName" variables.
You might try clearing your cache and cookies. We have been making minor updates recently and continue to make improvements to the service.
Also be sure to view at least 3 pages in the session before attempting to validate enrichment is occurring. Here is why:
The first page view sends the data to AudienceStream.
The second page view request the update from AS and writes the data into local storage.
The third page views reads local storage and injects the attribute data into the UDO.
Please give that a shot and let me know if you succeed or not.
