Although I know I can use the web version of gmail, the app on a Chromebook will not let you either reply or forward. It just opens a blank compose window. I'd much prefer to use the simpler app format for quick reviews and replies. This needs fixing Addendum after reply: Your link was to basic troubleshooting steps. And the forum your quote has many posts pointing out this bug and the "experts" say you need to contact the developers not us and they suggest using the store like I did. Didn't really help did it?
