Hi Reaper,
i've just got the same "problem" when trying to apply the Master-Pages spread properties to all as well as a specific set of pages, the dimensions are not being adjusted accordingly.
This also happend when just applying "clean" Master-Pages, on which only the Dimensions have been changed.
But since this is the first bug i found within 1 week of regular usage of Affinity Publisher I'm quite happy so far
keep on going
jerd got a reaction from Reaper7 in Master Margins to Page Margin Bug
