Few issues with the new DJay App

I am enjoying the new DJay app but have come across 3 issues with it.

  1. There is no analyze library button on the iPhone anymore.
  2. The keys of the song disappear when you go into 4 deck mode. So I cannot keep the key or match any of them.
  3. The looper function is great, but the beats are slightly behind when using Bluetooth headphones. If I direct headphone is plugged in, the beats are in sync but if using headphones, the loop beats or slightly out of sync.
