Split view two .pages documents
For some time now, my MacBook refuses to split view two .pages documents. For my work it is necessary to compare two documents, so it is much easier to split the screen. Not being able to do this is very annoying, seen as it was previously possible in MacOS Mojave. Is this just a bug or is this easily fixable? I have turned on "displays have separate spaces" in Mission Control, but this does not seem to be the problem.
Any helpful tips for fixing this issue?
