So I updated to this yesterday and I have a group message and I turned on the do not disturb on this group message and now I'm noticing that I don't get a notification on my phone? To explain more, on 8.1.2 I had the same settings and every time I received a text from the certain group message it would turn on my screen but it wouldn't vibrate. Also on 8.1.2 it would have the notification on the lock screen. But now in the beta it isn't doing that anymore. I was wondering, is this a bug or is this how it's suppose to actually be?
