Navigation in MS Word app in iOS 10.2.1

I am trying to use the Word app on my iPhone 6 running iOS 10.2.1 with VoiceOver and a bluetooth keyboard.

One problem I am having is when I try to navigate by words and/or highlight words. For example, with Quick Nav off, I can hit Coommand+RightArrow to move a word at a time just as I can in other apps.

However, if I try to use Command+LeftArrow to navigate backwards, nothing happens.

Any suggestions for navigating and editing in the Word app are appreciated.

What I have been doing thus far is to write my text in the Notes app and then copy and paste into Word. But this isn't ideal.

Thanks.
