For several months now I've been placing my phone into silent wherever I listen to music on my phone.
This has worked perfectly until the other day.
I recently noticed that my do not disturb settings had altered but it was easily changed back. But I later discoverd that even when my phone is in silent mode the music on Spotify, YouTube music or any other media app will drop for a brief second when a notification came through. This is something that never happened before and is pretty annoying.
