Re my site c---.com. My two other sites are ok.
For Jan 13, there is no premium. It doesnt say premium 0$, just no premium at all on the dashboard.
Also, the drop in revenue on the 13th and 14th is very sharp compared to Jan 8-12. But the pageviews havent dropped much. I had less visits on Jan 12 but higher revenue.
Could you check if there is a delay for Jan 13?
Or if there is a problem with the ads txt on c----.com that might be limiting the number of ads shown on the entire site?
