Is it DLNA content you have problems with?
No, it's regardless of source, so playing Deezer, TuneIn and local DLNA when the SoundHeart engage with indexing and harvesting just makes it pause for a few seconds to minute or fully stops playing music. So for now, I've been kicked back to version 2.2.20869.213293545 which improved the usability but still have problem with pauses when indexing and harvesting.
