I am using stock, basic Ubuntu 13.10. I have the Chromium Browser installed from the Software Center, and I have the Chromium web apps extension installed. I have ALL of the Unity web apps, and the Unity web app service apps installed, and they are the latest version, according to the terminal. I have the option to Notify me when a website can be run as an app setting selected in Chromium. My Google Account, and my Twitter Account are added in the Online Accounts settings for Ubuntu.
When I go to Gmail, or any supported website, I get NO notification, NO popup asking if I want to create a web app, NO option to create a web app, NOTHING. It is as if I have nothing at all installed. but I do. I installed them all from the terminal, and I have confirmed that everything is there. Every single web app shows up in my Unity Search, and the extension shows in my extensions for Chromium.
Every search I have done on a solution for this has come up with something that DOES NOT WORK for me, or that I have already done.
Please tell me what I am missing, because I really want to use this feature. Is there some setting I need to change in the browser that I haven't done or something else that I need to do?
