Nike+ app not playing Spotify playlists

[garage_door]

I saw that this was posted about before but there was never a resolution posted. I’m having a problem where my Spotify playlist stops playing through the Nike+ Run Club app, seemingly when my phone switches from WiFi to LTE. Once this happens, sometimes I can get it working again but usually it just freezes the whole music option. I’ve tried reinstalling both apps. I have data usage enabled for both. I’ve downloaded the playlists I want to use in the Spotify app to use them without WiFi and the issue will not go away. I can’t even just play Spotify separately from NRC because the music plays back so quietly when both are running separately for some reason.
