No ads are shown

Hello Google Admob Team,

I have a Unity game, first I used only Google Admob for advertisement, and after some time I changed to Ad Mediation on Admob, so integrated the plugins needed. 
It didn't bring those numbers after 5-6 months so I now decided to switch back to Google Admob ads only because it was better. All I did was create a new banner ad unit and set it up in the new game version. Users have already started downloading them, but for some reason there is no display/revenue associated with that banner id, I didn't turn off the banner used for mediation, I see that the number of requests there is constantly decreasing, so users who download the new version should see the new banner, but something is not right.
What could be the problem? In principle, the ad unit id seems to be good.
There were 31 displays of banner ad, but there should be much more.

Best,

Norb

Hi,

in the mean time I realized that the problem occurred because of a missing proguard rule. 

I set this rules in the produard file and then it worked.

# --- Google UMP (User Messaging Platform) ---
-keep class com.google.android.ump.** { *; }
-dontwarn com.google.android.ump.**

Are there any other necessary UMP rules too?

I use the Admob Mobile SDK 9.2.0 version.

Best,

Norb
