Bug in uTrack 24 with Master and 1 Slave

Hmmm. Strange.

So if the “M” and “S” are solid not blinking that’s mean the sync group formed properly and the two device are synchronized. In this case the buttons on the master are active but the transport buttons on the slave (Play; Record; Skip back; Skip FFD) are disabled, it shouldn’t have backlight. Is that correct in your setup?
So you said everything works properly except one scenario, where the sync group created, you start to playback the song then the song is over the next song properly pre-loaded on the master but not loaded on the slave?
