I’m experiencing an issue with AdMob ads in my VPN app where ads aren’t consistently showing impressions upon disconnecting. The ads are supposed to show every time the user disconnects from the VPN. According to my logcat outputs, the ads request, load, and supposedly show correctly, but impressions are only recorded once out of every four attempts. However, ads display perfectly every time upon connecting.

Thanks in advance!

I have done to resolve it as much as I can.
