I have linked the Mi Smart Clock with Spotify. Unfortunately, Spotify only reacts to my voice (i.e. only 1 song) and does not recognise any German songs. After that, the song that is playing appears on the display, but I can only select my entire playlist and the rest of the song selection by voice and not on the display. There is no menu, as I see in many YouTube explanatory videos. What am I doing wrong? I use an iPhone.
