Im on a mac and using a MS Digital Media Keyboard 3000, and when Im listening to anything on spotify, this buttons wont work, also the Stop button does not work however I dont mind that one. I know its not an incompatibility issue since these 3 keyboard buttons do work with iTunes and other apps, so this is a problem with Spotify.
A more detailed description, using numbered steps
1. I try to use the Next, Previous or Stop buttons found on my keyboard to control Spotify songs
2. It does not work.
What I expected to happen
That my keyboard hotkeys/buttons worked with Spotify
What actually happened
My Operating System
My Spotify version
My internet provider and country
Do you have any screenshots you can attach to more clearly explain your issue?
