GPS v21.0.0 = cannot find symbol method `getSnapshotFromBundle(Bundle)`

[Oldes]

When trying to build with the latest Google's Play Games Services (21.0.0) I'm getting:
cannot find symbol method getSnapshotFromBundle(Bundle)

android-basic-samples/CollectAllTheStars2/src/main/java/com/google/example/games/catt2/SnapshotCoordinator.java

Lines 207 to 209 in f6a39df

	public SnapshotMetadata getSnapshotFromBundle(Bundle bundle) {
	return SnapshotsClient.getSnapshotFromBundle(bundle);
	}

I wonder if Google will be so nice and will update its samples before updates will be necessary.
