Major Bugs with new Djay pro ios app (ipad)- Midi Mapping

One of many problems/issues with the newly released Djay pro ios app for ipad:
By remapping the big center placed Rotary Dial on the Reloop Mixon 4 to: PLAY SELECTED PREVIEW SONG “on press”, will shut down the Djay app completely/immediately, while this action is being done in the libary track tile view (not in the list view). Everyone be aware of this bug (one of soooo many unfortunately). I can not recommend using the app for anything where you want to shine as a DJ or simply get paid for. Unfortunately. Sidney
