Hi!
I have just noticed a sudden drop of over 60% in eCPM of all my AdMob ads in my Android app.
Banner eCPM dropped from about $0.40-0.50 to $0.08-0.10, Intestitials went from $5-6 to $2-2.5.
Same goes for number of clicks and CTR, so I suspect there's some problem in either of proper displaying of the ads, or with proper counting of user's clicks.
Was there any library or formal change, that could be causing such behaviour?
My app is still using play-services-ads:20.3.0 and I will be updating it in following weeks, but I am still working on some other things, that prevent the update. Also could using outdated library cause such clicks drop, while still counting some of them?
