Editing tool bar glitches – Microsoft Word Review

I’ve been trying to create myself a resume and the app glitches every time. The Edit tool bar above the key board disappears. Whenever I try to edit it literally disappears as if there is no editing tool bar. I’ll leave the app alone for hours, in hope it re-appears but it doesn’t. It’s disappointing and very frustrating.
