My Question or Issue

I installed the Spotify app (latest updated version 2.0.13 - although when installed it says version 2.56.3)  from the LG Content Store. The TV´s sound is connected via  HDMI ARC (working well with the TV and Youtube app) from a compatible Samsung Home Theatre. 

Strangely the app only plays the first track through the home theatre speakers, then it mutes for the next track, but if I change to the TV´s speakers it comes back again.

I read somewhere that if I reset the TV this would fix itself and it actually worked. So I was able to have ALL tracks´sound come out through the HDMI ARC connected home theatre. But after two days it happened again, so I reset the TV again and it came back. And now it is at it again.

It´s impossible to be resetting the TV everytime this happens because I loose all my personal config and have to do it all over again.

There´s clearly a bug in the app. Please advise!
