Players were able to use the Online Lounge feature of the Nintendo Switch Online app to arrange Splatoon 2 online battles using their smart device, such as by sending a URL link that allows social media friends to join a room.
As of July 28, 2021, the Nintendo Switch Online app does no longer support the Online Lounge feature. However, the app continues to allow friends to voice chat, and no changes will be made to the app's game-specific services at this time.
You can also continue to start a local or online multiplayer game in Splatoon 2 without use of the Online Lounge feature.
