DP has been rising very nicely for me all year, and then I also saw a significant drop ever since Dec 5.  I figured it could be  a best match shift, and if my guess were right, I'd see others talking about it here. 

Anyone else seeing Nov 30 listed as the first day of Dec and today is called Dec 6?  It hasn't always been this way, has it?  Is it me?

You are same in my case and I noticed calendar problem(30 November starts for December's first day) too.

But the selling problem seems abnormal, it is not like normal fluctuation in MS sector.
Thanks for all information.

It started slow, now is ok. But yes, ı have approval problem too that they accepted my files after "11" days. It ıs very surprising and i did not benefit from well my last uploads in that way.
