hello dear my admob adds is not showing after i export my apk file, in live campanion adds is showing but i export my file then adds is not showing
Do one thing, make all of your ads in test mode and then download apk. If they are showing as test ads come back to the creater and just turn off the test mode and update or publish your app. You will see ads after it appears on play store. Same happened with me but now fixed.
And can you add the error message on blocks
