ADMOB not working

my banner ads are not showing inside the game, i added the ad unit id from admob, added the app id from developer console it’s been a week and there is nothing happening,any ideas what is wrong ?

Mine too. no ads are showing after I upgraded my project to 4.20.2

not working for me too

Same here, first time I actually tried using them so I wasn’t sure if I was doing something wrong. Guess it’s not my fault then.

Same here too, It is used to be working fine but not anymore, even in 4.20.3.

I solved the error by restarting and clearing cache of “google play service” in device.
But after showing admob banner for a few times, the error appears again.

Restarting the game does not make the error disappear, until doing above method.
