I have this issue on a Galaxy S8 with Beats Solo 3 Wireless headphones. I have to close and re-open the app a few times to get it to work again. Reinstalling the app did not seem to completely fix the issue. Currently have spotify app version 184.108.40.2065. Skip/Previous functionality is not affected. The Google Play music app or other music apps are not affected.
Thanks for all the recent reports since our last update.
We can confirm that the tech team are still aware of this happening for some users, and will be working towards a solution.
We don't have an exact timeframe for a fix, but hopefully it'll be updated soon.
For now, we'd recommend keeping your app and all devices fully up-to-date.
