My Question or Issue

Sometimes I leave Spotify app to play something else but I can't. On Facebook, for instance, I try playing a video but it automatically stops after a very short period of time like 250-500 milliseconds. I have to kill Spotify so that the video on Facebook won't be paused out of anywhere. And today I noticed another app impacted by Spotify: Whatapp. I was trying to send a voice message using the mic, but the recording was being paused without no reason after a short period of time so that I couldn't record the message. After killing Spotify, I could record and send the message.
