Audio drops from videos when playing USB 3.0 iXpand drive on iPhone 7 and on iPad Air 2

if you are seeing the same issue with audio when using wired headphones this is likely a different issue not related to the BT update. I have tested on iPad air 2 and iphone 7 and I am not seeing any similar issue when playing any video file types. Not sure what could be causing it in your environment. can you let us know what file types you are using? maybe it is format related?
