We had the same experience with our google ads across multiple campaigns. Tried everything from increasing the tCPA and daily limits significantly, to creating campaigns in 1st world countries only. Around 80% of the installs just opened the app and closed it after few seconds without performing a single action, not even a tap! Google does not give you a detailed breakdown of where all the ad was shown within Google's services. They do give a breakdown of the 3rd party websites and apps where the ads ran and they are all terrible shorts drama and html5 games websites for me - some of them even had the same UI with different URLs! Shame. Ideally I would like my app's ad to be placed in the Play Store only, but Google doesn't allow this control conviniently. Next I am going to try using in-app actions for conversion instead of install, but I doubt it will be helpful at all.
