Google maps stopped working

Hello

MyApp uses Google maps, everything was working, but now it only shows like a generic map from Rome

As I just said, it was working, I have all the settings and permissions in place, like my api key from google etc.

On Android
`

<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<application android:label="MayApp" android:icon="@drawable/icon">
    <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="mykey" />
    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
    <meta-data android:name="android.max_aspect" android:value="ratio_float" />
<provider android:name="android.support.v4.content.FileProvider"
          android:authorities="MyApp.fileprovider"
          android:exported="false"
          android:grantUriPermissions="true">
  <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"></meta-data>
</provider>

`

In mainActivity.cs I make this call:
Xamarin.FormsGoogleMaps.Init(this, bundle);

On iOS
<key>NSLocationWhenInUseUsageDescription</key> <string>GPS</string> <key>NSLocationAlwaysUsageDescription</key> <string>GPS</string>
In AppDelegate.cs I make this call:
Xamarin.FormsGoogleMaps.Init(Variables.GOOGLE_MAPS_IOS_API_KEY);

Anyone has an idea why?
