If I click on the "+" button on my PC to save the Song in "my music", the music on the computer stops playing and instead, the music on my smartphone, which is in the same network as my computer and also running spotify, starts to play the Song. the computer doesn't recognize this, so it doesn't tell me that it's now playing from my phone, it just stops. If I click play on my computer, the music switches back to the computer. I use windows 10 on my PC and android 7.1.1 on my Phone. I first noticed this behaviour after the Android Spotify Update.
