Recommended content not shown in YouTube Scope.

[Gregory Opera]

When I access "recommended" videos, playlists or channels in the YouTube Scope, no content is shown.

bq Aquaris E5 HD Ubuntu Edition:
* OS build number: OTA-9
* Ubuntu Image part: 20160123.1

Reproduce:
- Open the YouTube Scope and ensure that you are logged-in.
- Select "Recommended for You" from the drop-down list at the top of the screen.
- Select "Videos" OR "Playlists" OR "Channels".
- Wait for animated "loading" bar at the bottom of the screen to stop moving (indicating that loading is complete).

Result:
YouTube Scope displays one of the following error messages (depending on which option was selected above - "Videos", "Playlists" or "Channels"):
- No video can be found in this channel.
- No playlist can be found in this channel.
- No channel can be found.

Expectation:
Recommended videos, playlists and channels are shown when the applicable option is selected in the YouTube Scope, as per what would normally be shown via the YouTube Web site.
