Try the different mode settings on the pedal itself. Each sends different commands. Sounds like it's sending tabs at the moment.

Thanks for the suggestion mdavej but the pedal works perfectly if I pair it with my android tablet so I think the problem is with the iPad/mobilesheets setup. The inability to turn off airturn is where I suspect the issue lies.

That pedal, if it's the one I think it is, has five different modes that each send different keypresses. If it's working with the Android tablet, it would make sense that it should work with the iPad too, but I would still try at least modes 1-3 and see if any of them allow you to set the keystrokes in the "Pedal Actions" settings.

On my iPad, if I tap "Airturn Direct Mode," then disable the "AirTurn Support" toggle, then tap outside the dialog, the dialog disappears and Airturn support remains off. This is on iPadOS 16.2, MobileSheets 3.6.7.

My pedal (different than OP's) sends screen swipes in Andriod mode that don't work at all in iPad mode. So claiming it should work on all platforms if it works on one is a fallacy. That's why it's worth trying the different modes in order to find iPad/MobileSheets friendly commands/keys.
