As far as I can tell, it does work with the Tidal app as I listen in balanced to Tidal offline and there is definitely an increase in power etc. UAPP, sadly, cannot play tidal offline....only streaming. Also, with the current update to UAPP, the volume has dropped considerably on the XDP and they can't seem to figure it out (at least it has on mine) making it pretty unusable. Give it a go on yours and see if you get the same issue. You'll have to make a quick switch over to Tidal app to see this difference.
