Also, I should point out that you can't view the play queue on iPhone at the present. But when you add song via the "add to queue" buttton, that's the song that should play next. Think of it as "move to the top of the queue once this song finsishes". Is it not workling for you that way?
I’m having the same problem. I want to add a searched for song to the queue or a playlist, rather than have it play straight away. The problem is the button to bring up the menu to select queue/playlist does not always work, causing the current song to stop and this one to start playing.
Search for a song.
From the song in the list of results, try to press the circle with dots button.
Most times when I do this the song starts playing, whereas I would expect the menu to appear.
Sometimes the menu does appear but usually not.
Perhaps the button could be bigger, or a swipe or push-and-hold action used?
I have an iPhone 5s. Spotify version is 18.104.22.1689.
Yeah, I've made a similar note about the buttons being too small on android. I don't think there is anything weird going on here other than failing to tap the "..." icon, if you miss and tap the track it plays which is annoying!
