Roku & Music - Keeps going to the Select User screen

The managed users work great on my Plex server / home network, with the only exception being if I’m listening to music on my Roku (I have a few different models, and this behavior is the same for all of them) after a few songs it takes me to the “Select User” screen. I’ve tried turning off screen savers (both Roku and Plex) and that does not work. Any suggestions that do not include automatic logins?
