Hi Andrey,
According to the article that you mentioned, it says that you should wait 3 days to appear the audience, but Andreas, mentioned that it happened more than 7 days.
I am experiencing a similar issue, where I exported an audience from Adobe Campain for more than 7 days, and I can see that there is population in the audience, but in the UI I can still see: "collecting data"
Have you found the solution to this?
Kind regards,
Ivan.-
