Indesign is hyphenating words wrong in Danish (after todays upgrade and upgrading to Windows 11). Document language is set to Danish in prefrences under Disctionary (which is set to proximity, Hunspell does not work either) and autocorrect. The paragraph style is also set to danish and the Hyphenation rules are as they always was. Text is copied from word to notebook to indesign and there is no - in the words from there (double checked). It is hyphenationg fx. wrong in tilgæn-gelige and forårsa-get and lejlighe-derne.
Did you select the text and make sure the language assigned is really Danish? Language is a character level attribute and has nothing to do with language specified in the Prefs, and might not match the paragraph style (a local override).
