The app works as long as I have bluetooth disabled. However, if bluetooth is on, the app instantly crashes. I have tried:
Logging out and logging in again.
Deleting and reinstalling the app.
Restarting the phone.
Reflashing the bluetooth firmware on the device.
Reflashing the firmware on the device.
Interestingly, turning on bluetooth while already inside the app will trigger an instacrash as well.
