Each time eM Client sends a notification on Windows and I respond by clicking an option absolutely nothing happens. I continuously get notifications about newer versions and click ‘upgrade’ and badoom, nothing! Same with the feedback notification.
Apparently the feedback notification is a know issue and is being looked at by the developers. Probably related to all the notification issues when using Windows system notifications options.
You can disable that option in Menu > Tools > Settings > General > Notifications until a service update that addresses this is released.
For the application updates, you can always just download the latest version from the Release History.
