What I did: I turned on “Check Spelling While Typing”, “Check Grammar…” and “Correct spelling automatically.” I get a red squigly line underneath the misspelled word or bad grammar.
What happened: when I right click on it to get alternate suggestions the suggestions appear but are greyed out and not able to be clicked/selected.
What I expected: I expected that the context menu would show alternative spellings and then give me the option to select one of them as a replacement. Instead, I had to retype the misspelled word on my own.
Things that might be helpful to know (Agenda version, OS and model, etc): I’m using mojave public beta 10 and Agenda 2.3.
