If you notice that your winnings are not counting towards the leaderboards, this could be due to the following reasons:
If your current country differs from the country when you first logged in on that week.
This will affect players who physically changed countries, or simply used a VPN to change their location.
Make sure that the country that is set remains the same throughout the whole week in order for the winnings to count for the leaderboard.
We have no way of manually changing the country. This is automatically set by the location of the device/settings.
Also, if you repeatedly played matches against the same player, those winnings will also not count.
