spelling mistakes, and accessing spelling suggestions in mac OS Sierra

Hello everyone,
I use to be able to press down arrow in previous versions of Mac Os to get the spelling suggestions and could press return to select it. However in Sierra, this doesn't appear to be working. When ever I press down arrow after a misspelled word, voiceover doesn't say anything. does this still work reliably? I should add that I have gotten this to work once or twice but it doesn't appear to be working reliably like it use to in el Capitan.
Thanks
