Firmware 2.02.32 | How to use P2P downloads with tablet?

The model no. is WDBGXT0000NBK-01

What I’m trying to do is use the WD TV Downloads app, to download a torrent to an external HD.
When I try to do this via the Nexus 10’s Chrome browser, I can’t add a torrent from File or URL, because the buttons aren’t responding.
I also tried the remote app (in case I was doing it wrong) but it doesn’t have an option for adding torrents.

With the tablet, I usually use the remote app instead of the browser page.

This is the 2nd torrent download I’m trying out, so P2P is still enabled & everything else works properly (the last torrent was added from my laptop). So I’m wondering if I’m still doing it wrong or if it just doesn’t work with the tablet.
