You may experience an issue with the ROLL App crashing on your Android device. This occurs when you have two Bluetooth devices connected to a ROLL with one being an Android device and the app running on that device. To fix this issue, try the following:
Disconnect the second Bluetooth device from your ROLL (either by disconnecting it from the Bluetooth devices menu or turning the Bluetooth connection off completely.)
Terminate and restart the ROLL App on the primary Bluetooth device.
If the above doesn’t work, try the following:
Turn your ROLL Off, then back On again
Terminate and restart the ROLL App
