I created a chrome extension and I released an update few days ago. As far as I know, when the user re-opening the browser or restarting his pc, chrome should auto update the extensions automatically. However, I noticed that for some of my users, even when they restarted their pc, they still on an old version of the extension and it won't auto update.
The current newest version is 1.3.2. I uploaded it few days ago. Some of the users are still on version 1.3.1 even though they restarted their pc.
Why does it happen? As far as I know there is no option to disable auto-update of extensions..
UPDATE:
