As a result, you may find that you can no longer use the “C-Connection Chrome app” on your current Chromebook. In light of this, we are redesigning the app as the “C-Connection Chrome extension” so that you can use it with your Chrome browser even after January. Install the C-Connection Chrome extension to ensure that you can continue using this functionality with your Chromebook. • The redesigned C-Connection Chrome extension offers a number of functions that differ from the current app.
