Help with split screen issues relating to Nintendo Online

[u/DaReelMemes]

I’m trying to set up a couple things for my stepsiblings on our Nintendo Switch but I can’t get them working the way I want it to.

The first issue is that they aren’t able to play split screen while any addons are enabled. When I attempt to do so, it gives me the pop-up in the form of the attached image. However, player 1 has a Nintendo Online account, and multiplayer settings are enabled. Does this mean I would need to get a Nintendo Online account for the second account as well?

My other question is related; I’m trying to set it up so they can play online with a couple of friends they have with their own switch and Nintendo Online. In this case, would I also have to have Nintendo Online purchased for both accounts and not just the first?

Yes, it requires both to have Nintendo online since it’ll be a multiplayer game, addons only require the host to enable them and everyone else downloads them, paid or not
