OK. I can see a number of posts of this topic before, but about specific notifications.
Myself, I have a suspicious connection blocked message that appears up to 20 times a minute (it's something to do with my clients Teams site). I am very happy the connection is blocked, but I am not happy I cannot turn this specific notification off or mute it!
When a notification pops up, I can no longer type in which ever application I'm using until I re-click within that application. When I'm this happens 20 times a minute, I can no longer work effectively. When I no longer can work effectively, I look for other virus protection products.
I understand security alert notifications are important but I would recommend you provide the facility to mute notifications or specific notifications or you'll lose customers.
