Please migrate your app(s) to Vungle v.3.3.0 or higher as soon as possible and increment the version number of the upgraded APK. Google Play will block publishing of any new apps and updates that use pre-3.3.0 versions of Vungle. If you are using a 3rd party library that includes Vungle, please notify the 3rd party and work with them to address the issue.
