I updated to the new version (10) and under windows 11, when receiving a new email I no longer get a taskbar icon blink. The system tray still changes to a mail icon, but I don’t typically minimize my email client to the system tray, I usually keep it open in the background.
Would definitely like the orange highlight to return as I can see it better than the system tray mail icon, catches my eye more, allows me to see I’ve got new emails quicker.
