InDesign is forcing horizontal-only mode on my Surface Pro 4. Is it not possible to use InDesign in vertical mode?
Admittedly, the orientation sensor can be a little weird, but I've eliminated that as a variable. In both desktop and tablet mode, I'll be in vertical, and if I switch to InDesign, the screen "rotates" back to horizontal, even though I haven't moved the device. As soon as InDesign is not longer active (touching the start button, for example), it immediately switches back to vertical.
Is there an "allow vertical mode" option that I'm missing somewhere?
