Haha, more is good 🙂 Sadly I haven't a clue why the queue button is missing. I thought it might be down to the Moto's soft buttons but other Moto owners haven't been complaining. All I can suggest is to try a clean reinstall - follow the instructions in the first part of this post.
If that doesn't fix things, use the online contact form and someone at Spotify can help get this sorted. If you get an automated response directing you back to the community or to the help pages, please reply to it by email and you will hear back from one of the team shortly.
I'd be interested to hear the eventual solution 🙂
