Notifications not staying
Chrome users on Windows 10 are going to start seeing Chrome notifications delivered as regular Windows notifications. This means that the Chrome notifications will use the same styling as Windows notifications and that they’ll all show up in the Action Center. this is great for home users but not so good for business users. Programs like Google hangouts, ConnectedShop, and OnBoard Scheduler will only show the notification for the default of 5 seconds, that means may miss a chat or an upcoming event.
The current workaround is to change back to the old way
Open Chrome and in the address bar copy and paste this link
And change enable native notifications to disabled
