While using crossfade option on my Nokia 8 Sirocco with Android Pie sound beginns to stutter after changing to next track. No stuttered sound while skipping manually to the next track. Same effect with Google Pixel XL (1st. Generstion) on Android Pie. ZTE Axon 7 with Android Oreo plays flawless. Any ideas?
