It does not work in FFA at all. I set 1600+ or 1500+ and then play a game with 3 1300+ guys.
CHANGELOG

i set it 1400-1500 and all my opponents in the game were exaclty that, 1400-1500. haven't tried teams. but keep us posted if it continues not to work for you.

Do you have a list of games played today? Look at my opponents ratings then. I did not set it lower than 1500+, but there were lots of 1200, 1300 and 1400 guys.

Sad to hear it does not work @BabYagun. We really hoped it had been fixed now. I removed it from the changelog for now. We will investigate.

The tabs design is a nice visual improvement. About the rating range setting, I can confirm that it's not working properly. I just played 2 games where my preference was ignored. I don't know if it is a browser issue or a server issue. After the first game I changed my preference a bit, to see if that would make any difference, but the issue was not solved.
Browser: Brave 0.20.42

2nd game:

It is most likely a server issue. Thanks anyway, @Skeftomilos, glad to hear you like the new design.

Yes, it looks much more polished and professional now. Let me post a screenshot in case it is changed again in the future.

May be rating range is fixed in FFA, but not in teams when one invites a teammate. I just played a game versus 1100+1200, however the range selector is 1500+.

I tested multiple times. In Teams the selector does not work, at least when you invite a teammate. I did not test it without the invitation.

No idea why it would not work for you @BabYagun, it seems to be working for everyone else. Was it you that sent the invite?

Yes, I sent the invites. I played more than 10 games with @joselito1984 today. He can confirm that we played against 1000 to 1300 opponents several times. And the range selector is on 1500+. Note: both the opponents were out of range, not one of them.
If you want, I will tell you my password, you can play using my account for a day. Or just create a new account, set its 4PC rating to 2200 (as I have now) and test it.
A screenshot with 1059 and 1215 guys playing against 1801 and 2156:

Today changed the selector to 1500-2900 (instead of 1500-3000), played a few games with Haunted_House (invited him in all those games) and the rating range selector worked fine.

ok, glad to hear it works for you. I have seen it working for players rated above 2500, so I was pretty sure your rating was not the issue.

Well, sorry to say that, but it does not work. It works most of the times. But still allows games like this one:
it works, but you have to set it. it only doesnt work if you haven't changed it since the update
