+Playing through the relay
+Playing together through the relay — agreed
When two players' networks can't connect directly, the game goes through NESER's relay in Sweden. Players see this in the Connected view and on the chip. Everything not shown is unchanged from the room-code, internet-play and Play together drawings.
First window — the address line now mentions the relay (always shown; wraps on a phone)

ⓘ Playing together connects your computer to the other player's — directly, or through NESER's relay when it has to — so each of you can see the other's internet address.

Too slow to play
The connection through NESER's relay is too slow for the game to keep up. A direct connection is usually faster — try again with both of you on a home network, ideally wired.

↪ Connected through NESER's relay in Sweden, because your networks don't allow a direct connection. This can add a little delay.
The connection through NESER's relay has become too slow to play. It may recover by itself — if not, try again with both of you on a home network, ideally wired.

Couldn't connect your two computers. Your networks blocked every way of connecting them, even through NESER's relay. This can happen on strict work or school networks — try again from another network.

These replace the earlier “Couldn't connect your two computers. Your networks don't allow a direct connection between them…”. While trying, the waiting lines and the roughly 10-second limit are unchanged.
