Hi. What makes it so difficult to search among your albums, artists, playlists, or tracks on Tidal from within the Volumio UI?
Regarding connectivity, you may be having internal network issues. I imagine that “loses contact frequently” means the Volumio app on your tablet and your Rivo fall out of sync every now and then?
Just out of curiosity, if you open Safari within your tablet and type in your Rivo’s name + .local in the address bar, do you experience the same behaviour? The address should be “yourdevicename.local” to test.
