I have been using the free version of volumio for years, ever since Logitech discontinued the squeezebox music player. It is setup on a Raspberry Pi SBC using a Hifiberry Digi hat to send data to the DAC in my amplifier. I have a music library of FLAC files. In this configuration it works flawlessly. Highly recommended. The volumio android phone app works very well and is highly functional. I recently upgraded to Myvolumio in order to use Tidal. This interface is a bit buggy and is representative of a 1.0 software version. The connection between the Tidal Connect on the phone and the volumio server is problematic. Some tracks play seamlessly, others stall after a few seconds and some never start to play. It is better to research the tracks you want and then play them directly from the Tidal/Volumio interface. There playback is seamless at that point. However, the Tidal interface on volumio is not as feature rich as Tidal Connect. Also, it is nearly impossible to add favorites from the interface. I have only had partial success in adding favorites from Tidal Connect on my phone, and then have them show up on the Tidal volumio interface. Even with these issues, the value proposition for Volumio is quite strong as I have to spend several hundred dollars more to get a network streamer with strong Tidal support. I am certain that the issues will be resolved in future updates. For that reason I haven't given up on myvolumio/Tidal. I am anxious and can't wait to see the interface improved.
