Notifications don't work

Notifications don’t work

I have created different projects and my teammates work with me on these projects but I can’t see any notifications. In the User settings, I see something strange : The icon is not a bell, but something else


I have tried to reactivate my account, it seemed to work, the icon changed and became a bell, but just after few minutes, it came back to the same icon, still without any notifications.
I’ve changed to have all the notifications, but there is still the same problem, I don’t have any emails at all. Could you help me please?
