What is the correct way to update customer attributes for already uploaded CRM IDs? For example when customer changes age group or segment.
Case in point: I have uploaded a test customer with attribute "Age" as 29. I have previously logged in as this customer, and I see visits where Age=29 in Analytics. So far so good.
I then upload a new file with the same customer included, but Age is now 30. I then log in as this customer (after the file has been succesfully ingested). I wait for the data to show up in Analytics, but Age for this customer still shows 29. If I use "Preview Data" under customer attributes, it also still shows 29 for this customer.
Out of curiosity has the Data completed processing, found this to be the case with classification data, file transport has occurred but still processing the data within Adobe.
