Spell Check in Messages App in Big Sur

Forum
macOS & Mac Apps

I recently updated to Big Sur. I have found that, when I spell check in the messages app, when it highlights a misspelled word, and I do VO shift M, to bring up the context menu to get suggestions, VO is silent. Spell check still works as expected in other apps. Can anyone offer me any guidance with regard to how to get around this problem?
