As with any pedal, the first thing you should do is check the configuration. Please follow these steps:

1) Load MobileSheets, tap the three dots at the top right and then Settings.
2) Tap Touch & Pedal Settings and then Pedal Actions
3) Tap the "Keys" field for Pedal 1.
4) Tap the "Clear" button on the dialog.
5) Press a pedal switch. If a key shows up, that's a good sign. If it does not, the pedal is not communicating properly with your device.
6) If a key shows up, tap OK, then select the action you want that pedal to trigger from the dropdown below the keys field. Repeat these steps for pedal 2.

The question is whether you have configured the right key command for the pedal action to go to the previous page.
