Can be as simple as a line of text stating this as I don't always remember the previous day's number and then can't be sure. Should be useful for cases when people can't be present for a long time some days because of appointments etc.

There already is a display for how many more days until an extra reward due to milestones in the streak number, this would be a good place to add an additional text line displaying this information, making it "Streak counted for today! <br> 2 more streams until extra 350 reward"

I personally lost a 184 stream streak earlier despite being present and chatting the stream before and I would like to avoid such things happening to others.
