Cannot change Alarm music with Tidal

Since the last update to my Play One and S2

app, I can no longer adjust the music on any alarms, new or existing.

i have a series of Alarms with music defined, that leverages Tidal. I change the music every now and again to reflect what I’m currently listening to.

Alarms with existing tracks/albums/playlists chosen from Tidal work as expected. 
 

if I try and create a new alarm, I can’t choose music from tidal. I see the top level categories (Artists, Albums, etc), but can’t browse them, the app selects the category instead.

If I try and create an alarm using another service (amazon prime for example) I can browse fine.

From within the main music part of the application, I can browse Tidal as usual and can play music directly. 

There seems to be a bug/regression or similar that has broken the browsing function within the alarm, but only for tidal.
 

I’ve tried deleting and reinstalling the app,,to no avail. 
 

Any ideas?

Thanks

Dan
