Following a bug found in its Ver1.2.1 update, Nintendo has taken the Nintendo Switch Sports servers offline while it works to fix the problem. This means online play and save data backup are both currently down.

Nintendo shared the update on Twitter, saying this bug has been causing the game to close during the pre-match loading screen for some players.

“A bug has been found in the #NintendoSwitchSports Ver1.2.1 update which causes the software to close during the pre-match loading screen,” Nintendo wrote. “This is unfortunately affecting both online and offline play modes. We have therefore temporarily suspended the rollout of this update.

“While we investigate to find a solution, #NintendoSwitchSports servers will be temporarily taken offline and online play will not be available during this time. Save data backup is also temporarily suspended. We sincerely apologize for the inconvenience.”

There has been no timetable given for a fix, but we will update this story as soon as an update is given.

In our Nintendo Switch Sports review, we said that it “successfully recaptures the party game magic of Wii Sports, but quickly falls victim to a lack of depth that holds it back from achieving greatness.”

That lack of depth will be addressed this holiday when Golf arrives to Nintendo Switch Sports as a free update. The Golf mode will include 21 holes from the original Wii Sports series alongside a new Survival Golf mode. The update was initially set to arrive this fall, but was delayed by a bit.
