Shield client not registering?

I noticed that an nVidia Shield client never seems to appear in the client history list (on the clients tab of the Server GUI). It's been active for the past few days, even right at this moment. Is there a way I can get it to appear in the clients list?

If it's only accessing a HDHR tuner and tuner sharing is off on the client, the server won't see it.

It appears to be using a TVE tuner. I thought I had tuner sharing on, but I'll have to check.

Not related to tuner sharing.

What version of the app is on that device?

I don't know. How would I check that on a Shield device?

Settings > Support > About inside Channels app

Will check.

Mine is working on:

SHIELD

Channels v4.0.1

NVIDIA SHIELD
