Multiple restarts on both the laptop and the decks. It does the same logical dance every time of getting me to approve access via Engine on the laptop but it’s still ‘no tracks found’ thereafter.
I’ve seen this thread: Remote library on v3.0.0 times out and am checking my modem’s admin settings but there’s no mention of terms like multicast or IGMP (it’s a bog standard home router from Sky here in the UK with security set to WPA2) … And it would feel funny to me that this is the issue when it can see all the playlists. I’m not getting the same error they were getting in that thread.
I also set up a totally new playlist - which the decks saw instantly - and added those MP3 files to it but still ‘no tracks found’.
