I am regularly posting Facebook ads for my android app in playstore. My Facebook ads campaigns are not showing any data for columns like Results, Mobile App install, Cost per app install. I want to track the app installs from the ad clicks. It just shows a dash '-' line instead. I have connected my facebook ads manager with Facebook developer account and configured sdks in android app built with Flutter. I have also added objective as App Installs while starting campaign. I am using FB login for app for a year without any issue. Having this issue for sometime now. Any help would be appreciated. TIA
I have read and already followed steps from following pages: https://developers.facebook.com/docs/app-ads/measuring/measuring-using-facebook-analytics/
