Neither autocorrect or hyphenation working in Pages 7.0.1
I am using Pages Version 7.0.1 under High Sierra. I have selected autocorrect in Page Preferences, but it does not work. No underlining of misspelled words. I am able to use the search for misspelled words. Also, hyphenation does not work. I have de-selected Remove Paragraph Hyphenation in the Text>More panel, but no words are hyphenated. Are these problems related? How do I fix them?
MacBook Air, macOS Sierra (10.12.3), Pages '09
