Concur with this. @gabriel.engel you guys really need to have an option - on by default - that does not send a mobile push notification for any messages that have already been read via web app or desktop app. I am constantly receiving push notifications well after I read something on the desktop app - and by “read” I mean the desktop app has marked it as read.
This also - important for admins to be able to override user’s notification settings.
Neither of these things are urgent unless you are charging people for push notifications. But they become urgent in that case. If you are charging people for use of a service, I think you have to give them reasonable ways to control the usage of that service.
