Hello @MuOliveira, are you on Spotify Premium? If so, thats odd. You can try to forward with SHIFT + RIGHT ARROW and see if that will work for you. If it works, that can be some temporary bug, that would vanish soon.
If you`re on Spotify Free, forward is not a feature for free users.
Hope that was helpful for you!
