Spotify Lossless is finally (or going to be) released (to some regions such as Australia, Austria, Czechia, Denmark, Germany, Japan, New Zealand, the Netherlands, Portugal, Sweden, the US, and the UK).
If there is any Lumin Spotify user here who has already got access to Lossless streaming, please update your Spotify app, configure Media Quality to Lossless, and try it with Lumin. (If you don’t see that, you’re not in a launched region or your account has not got it yet).

Please let me know if there is anyone who got it working with Lumin.
All Lumin streamer models should support it.
