They've mentioned that it will be looked into for a future release.

I'm able to play the served music on the tablet. Just can't send it to any other renderer. Is this something in the works?

MMA can only play from servers.

What about the Android version? I cannot find renderers on it.

Alternative option is Tools > Options > Player.

Whoa! Found it! It is actually the bar all along the bottom of the screen with song title and play-progress bar.
Did NOT see that coming! Thanks! All set!

I see the Media Servers node. No problem there. Not seeing "Player". Is that a node?

DLNA servers should be in the Media Servers node in MediaMonkey and clients should be with Right click on Player > Choose Player.

I am not seeing any of my UPnP/DLNA devices. Where should I see those? Never have.

I thought I'd share this with everybody.

For no apparent reason, my Oppo blu ray player stopped showing up in Mediamonkey, in the UPnP/DLNA player select box.

What I did was to unplug the blu ray player and then replug it in. That forces the network to re-establish a network connection with your computer. The blu ray player most likely was still running off your router, happily delivering netflix or whatever you have streaming across your internet. But by rebooting your DLNA device by depriving it of any electricity. it will force the device + router + computer to re-establish it's connection.

Also, some devices might has an alternative way to force a hard reset.
