I am not sure why this is causing.
I have been trying to figure this out for a whole day.
Now realized that disabling any of the inbuilt plugin will stop Admob interstitial test ads. Don’t know how this is related.
Don’t really care anymore now after wasting so much time.
If someone figure this out later please post your answer here.
I want to remove all unnecessary plugins from my build.
Current development apk is 100 mb with only 10mb of my content and with compressed option ticked in project setting.
It was reached to around 60mb but enabling and disabling plugins probably made it 100mb
