My Google Maps API Id stopped working

I have an Android app and are no longer loading the bookmarks on the map, an application that is active in the Google Play Store, has not been updated in the apk, has not changed the key in the Google Cloud Console, simply stopped. I already checked the Android Studio Logcat and everything is ok. In the last month Google changed its name from Google Console Maps to Google Cloud Console and changed internal policies, such as the obligation to register how to charge your services, although they give credit and I already carry out this operation yet my application is affected . Has anyone had a problem with Google Maps API authentication in this change? If anyone has an idea of what can be, thank you.
