I've tried to log into my friends world today countless times but it would always end it up with the same screen saying "error:p2p/sig no_session(3)", and honestly I don't know what to do anymore. I've tried logging out of my Microsoft account and logging in right afterwards, I've tried to restart my switch, I've tried to restart my internet, but none of them worked.
Thank you for your report!
