I use other than volumio’s own control app for streaming; hifi cast, it works pretty fine for me. With v3 it no longer plays in gapless and randomly stops at the end of each track. Most of the time. I tried other apps; mconnect, Bubble UPnP, Media Monkey … they all showed the same behavior. Volumio’s own app is does play continuously, but when streaming from AssetUPnP it does not play the first song in the folder, which means the last song can not be played either unless the track before it is selected. So the selected tracks do not in fact get selected, but only the tracks after it. Same is with the web interface. Volumio2 is the same, but at least it could play without stops when controlled with the 3rd party apps, which worked quite nicely for me.
