Poor setup instructions and UI initiation. Not user friendly for setup and initiation of VOLUMIO UI. Took me 3 weeks to figure out! Get rid of on screen login to initiate VOLUMIO UI after setup. Replace VOLUMIO App login Green Play button with the words,"START, OPEN or NEXT", because I would not select the Green Play button for 3 weeks, because I had not selected a particular music file or Radio stream to play yet. VERY MISLEADING AND CONFUSING! The Favorites selection process is confusing as to where to find your selected Favorites. Seemscto be 2 different types of Favorites locations. Either have only 1 or label them separately. Lots of online Radio stations have multiple folders of the same station under the same folder. Eliminate duplicates. I once found about 8 of the same online Radio streams under different selections in the same subfolder. You sometimes have to select the same Radio station multiple times before the error message(s) go away and the Radio station plays. But the basic layout and organization of the UI is good, but needs work to become user friendly.
