Good App and hardware, poor documentation – BT Bluetooth MIDI Pedal Editor Review

I recently purchased the Positive Grid BT-4 pedal and downloaded the app on my iPad Air 2. No problem connecting the pedal to the app, and using the pedal to control BiasFx worked fine. I also wanted to use the pedal to control the Loopy app and there were some brief instructions on configuring the pedal on the Positive Grid website. I was eventually able to get it to work, but using the instructions caused a significant delay between pressing a switch and Loopy responding. Eventually I was able to figure out how to fix the problem. I then discovered that after I exited the app and restarted that my configuration changes were gone. Only after much fiddling did I discover that it was necessary to select the check mark on the upper right of the configuration window to actually save your info. Similarly I discovered that you can rename or delete a bank by swiping it to the right. Neither of these were documented anywhere I could find. I would give this five stars if the documentation were more complete including all of the controls in the app and information on which midi messages are sent and when ( button down or button up?, etc)
