I've just received my Digi+ and it's working well. I'm using it with Rasplex on a Pi Zero W*. However, every few seconds a message pops up in Plex saying "Remote disconnected: HiFiBerry" then almost immediately "remote connected: HiFiBerry". I've tried wiggling the boards to check for a loose connection but this doesn't make any difference to the frequency of the message. Two questions: what else could be causing this, and what is the remote function on the Digi+?
*I know this is not a recommended solution, but I'm only using it as a headless audio player. I may upgrade to a 3B anyway.
