Has anyone noticed change in admob impressions and CTR numbers in last week. I have noticed 10-15% drop in impression numbers for all my apps although download numbers are constant. Thanks.
Yes i have experienced the same and is bothering me very much, first i thought there is someting wrong with Appodeal(i use Admob with Appodeal).
Page views are higher but impressions, clicks and ecpm are lower.
Any Admob users notice something different?
For me it started on november 30.
Unfortunately same here 
It may not be related only to admob. Check your apps stats (not only downloads but also uninstalls).
Bump because this is important, maybe Admob changed something.
