I have used the Chrome browser on other platforms and over time I have purchased or added a couple applications (Journey, Keep, Writer). If I stick with the built in Chromium Browser as default and I sign in these applications become available for use. I can find them via search on the desktop, however I can not add them to the desktop. I do pin them to the task bar and everything works fine.
If I change over to the Chrome browser as default however it prevents these applications from starting up. I can still find them via search, and select them from the taskbar, but they no longer launch. I can still get to them and use them from within the Chrome browser, but not use them independently on the desktop.
I set up a couple other accounts on the computer. On one I started right of installing Chrome and setting as a default. That produces applications that show up in search, but do not launch. On the other account, I set up Chromium as the default got the applications with Chromium, which worked fine. I then installed and setup the Chrome browser, which resulted in blocking the applications from working.
In my case anyway the only way one can use Chrome applications on the desktop, is to set them up via the Chromium browser and never use/uninstall the Chrome browser. I speculate this is some issue with determining defaults. The Chrome applications will work with either Chrome or Chromium, but do not work when both browsers are installed.
