So, I have a Galaxy S8, pretty nice phone.
The issue I have with (it) is that notifcation do not dissapear from the phone screen after I read on PC.
I have it open on PC. I receive a message, I get notication on the Phone, I read the message on PC, respond to it etc. Notification still "unread" on the phone.
Same goes goes for mail, with which I tried several different apps.
