Hi,
just following up myself here; As Deke already mentioned, you will get the payment as well as the sales report latest 45 days after a months end. So the report for december should be arriving in around 2-3 weeks then (end of december + ~45 days).
It was the same for me, my asset was live on 26th of November, and just around 1 week ago i got the sales report for the november period.
The only thing is that i would also love to get the sales report a bit more in advance. Not talking about daily stuff here, but i.e. one week after months end would be really nice.
Cheers,
