I’ve been wanting to report this glitch for a while, but now having a game with such a difference in visits within 2 days, the evidence here is really visible.
The hourly graph is accurate, but the daily graph is a day off. And this should be fixed for the sake of accuracy in Developer Stats.
This happens with the traffic measurement as well as revenue.
It started happening when the Promotion tab was launched. In fact, the promotion tab is also a day off, however, the hourly one is fine. If needed I can provide another comparison picture for Promotion tab just as I did for traffic. (There is a huge difference)
