Preview external page turn command doesn't work in iPadOS 26
I play in a band and use my iPad on some songs to display chord sheets. I'd set up a switch to send an "Arrow Down" command that would turn the pages, which worked fine in the old Files app, but with the upgrade to iPadOS 26, it's now calling up the Preview app, and that command only works if the sidebar is showing, which isn't optimal since it shrinks the display of the file (and my eyes are old).
Does anyone know of a workaround to this?
iPad Pro, iPadOS 26
