"Wow this server is popular" connecting to shared world.

Often I get a "wow this server is popular" message when attempting to join servers that say e.g. "2/8" players. These servers do not have their player count limited to 2 (verified in settings).

It seems the error message is not correct.

The true cause is unknown. It happens consistently when attempting to join a game started on the Switch version.

It didn't used to happen. I used to play with people on their Switch regularly. I have not been able to join a single game, however, in a couple of weeks.

I have no additional information.
