Hello community,
I remember on windows 7 with google chrome, when minimizing a window the number of notifications appeared on the minimized window icon, being possible to check the number of unread email messages for example. I used the email page as a shortcut with the feature ("C: \ Program Files (x86) \ Microsoft \ Edge \ Application \ msedge.exe" --app = https: // ......) . Just as they appear on the icons of android applications. I found that if you use "pin to taskbar" by checking and unchecking the feature, it works like a bug.
I use "website as an application" in the company to access the email client. It would be interesting if this feature works normally.
