I switched from Amazon to Quboz after the last software update crippled AMHD. Things that I thought were BluOs related are actually shortcomings of the streaming service itself. Sometimes I search for something under the artist name and nothing comes up, but if I search for the specific title it finds it, but it's still not showing under the artist releases.
I suspect the issue is with Amazon, not BluOs. Not enough servers, app updates not yet shared with external services,etc. If you like your Node, I would be a little patient.
A simple workaround is to add what you want in the Amazon app as a favorite, then open it in BluOs from your library. Then you can save it as a BluOs playlist.
