If you are using an Apple mobile device (iPhone, iPad , etc) you may come across the following pop-up message inside the new InnuOS Sense APP.
If by chance you do come across this randomly appearing message: “Undo type”, do not worry, it is not a bug, nor an error with your APP. It is the “Shake to Undo” feature in iOS.
This was probably the result of you moving your device a bit too abruptly, and you can cancel it, and no harm will come to your APP or your files.
Enjoy your music!
