Skipping/pausing tracks impossible via bluetooth

[Section_M]

Hi experts!

I've recently upgraded my Spotify app on Android to version 5.5.0.653 on my Samsung Galaxy S5.
Since the upgrade, I cannot skip or pause tracks with the buttons of my bluetooth headset or with the buttons of my car stereo.

Before, everything worked fine when I connected my phone with my headset or with the car stereo via bluetooth.

Does anyone else have the same problem or have an idea how to solve this?

Thanks in advance for your help!
