I don’t really see a problem with that.

and I do, because it doubles the amount of notifications I receive. if 5 people ask me something that way, I end up with 10 notifications, half of them being a pointless “hey”. it’s just plain inconsiderate.

Also it shouldn’t vibrate if you’re already in the chat

I don’t always immediately rush to check my phone when I get notified, especially when the alerts are fired in a rapid sequence like that.
