Hi. Some covers are not displaying correctly, they are duplicated in different songs. The audio is delayed 1 or 2 seconds since I hit play with some True Wireles headphones and can’t mix the songs well, I have JBL Tune 120TWS. I have tried with the JBL T110BT and it sounds good, without delay (from the second 0), just like with a usb headset. However with the JBL True Wireles when I hit play it takes 1 or 2 seconds to start being heard. With a players (Jetaudio, Poweramp, etc…) not happen.
