Writing tools - no arrows to review each change one by one

Writing tools work as expected in Notes and appear to be quite useful, with proofreading being the most useful to me. However, in most other apps I use, there are no arrows to review each proofreading change one by one and no UI element indicating what changes have been made. This essentially makes writing tools fairly useless outside of Notes, as ‘all are nothing’ blind changes are not usable when reviewing text. Is this the same for everyone? Is it a bug on my devices? Any ideas on how to fix this or if an update will likely fix it? I’d really like to be able to use the full proofreading feature with Word and Outlook.
