Currently I am upgrading MoPub in Android from 4.8.0 to 4.11.0. When I am debugging the app, ads are shown fine. When I generate a signed apk and deploy to a device, no ads are shown. All I did is change the dependency version. What can be the reason for this? Even upgrading it to 4.9.0 doesn't work
(note debugging the apk, ads are shown perfectly fine. When signing it, no ad events are being triggered like onBAnnerLoaded or onBannerFailed).
