I can’t change the canvas orientation between landscape or portrait. Changing it in the Inspector pallet has no effect. Neither has setting the Inspector to ‘Use Page Setup’, and changing it there.
I’m running Mojave 10.14.6 (18G103) and OmniGraffle 7.11.4 (v196.15 r337417).
Am I doing something wrong? If not, anyone else have this problem?
