Notifications not working on Teams on Windows 7

Copper Contributor
Good evening,
I just installed teams on Windows 7. All works except notifications.
If somebody send me a chat no notifications appear on desktop. Also if somebody mention me.
In settings notification are on with banner.
The only thing that change is the teams icon in the trat that became red when somebody write me but no notification.

I read lot of people having this problem but no solutions.

Hope anybody can help me.

Regards
