Weird problems with synced Local Files and Bluetooth headphones

[user-removed]

I have several songs synced over to my Android phone and I added them to some of my playlists. On my phone, I keep all of my playlists downloaded for offline listening. Whenever I get to a point in a playlist where a song that is available on Spotify (so not a synced file) transitions to one of my synced files, the audio stops and doesn't resume until I reach another song that's not a synced file. In the meantime, there will be no sound, but the timer is going still, as if it's actually playing the song. If I manually skip forward and then immediately skip back, the song plays just fine and will continue to play songs afterwards regardless of their source until I get to another Spotify --> Local File transition. If I start the playlist on one of the synced files, it will play perfectly fine, again, until I get to a Spotify --> Local File transition.

This problem only happens when I've got my phone paired to my Bluetooth headphones. It doesn't have this issue when connected to wired headphones or just playing out of the phone's loudspeaker.

I'm using Spotify app version 8.4.3.479 armV7
