Regarding a kindly reply to a Twitter conversation (please find below) about custom hyphenation dictionaries support on Mac OS:
Is it possible / applicable to have a different folder location for the secondary languages (i.e. Turkish in this case) other than the default one located in Affinity Publisher.app package* itself — in one of the next updates may be?
Otherwise (or without any other reliable — more consistent solution), please be informed that, we lost language specific hyphens on a file and all the text styles drop auto-hyphenation to none in it, after an update. New version overwrites the app, so all the custom additions in package contents, of course.

Also please see this topic (says there is a minor discrepancy between Windows and Mac OS versions Preferences, Tools panel, “Additional dictionary folder” line. Mac OS doesn’t have one):
