Twilo 6.2.1 Remote Thumbnail Not Available

Question

I upgraded my Android application to use Twilio Video SDK v6.2.1 using the migration guide. The application allows users to communicate via video with people in an office; the office side uses a web application to interact with them. Since updating the SDK version to 6.2.1 the website no longer shows a thumbnail of the user, but a large 'primary view' is still visible. (Yes, there should be the large 'main display' and a redundant thumbnail view of the phone user.)

Is there something that should be specified within the Android application to enable the thumbnail on the remote side?

Figured this out, you have to specify a track name for the remote participant to display a thumbnail.

Using this constructor works:

public static LocalVideoTrack create(@NonNull Context context,
                                     boolean enabled,
                                     @NonNull VideoCapturer videoCapturer,
                                     @Nullable VideoFormat videoFormat,
                                     @Nullable String name)

This constructor does not (notice the missing parameter, 'name'):

public static LocalVideoTrack create(@NonNull Context context,
                                     boolean enabled,
                                     @NonNull VideoCapturer videoCapturer,
                                     @Nullable VideoFormat videoFormat)
