I can't help but think that this is intentional from Nintendo. There are many many online and local wireless features on the Wii/ and 3/DS that are no longer present on the Switch. They seems to start over with every platform. I get the impression though that Nintendo doesn't want communication features that are not "safe" for younger players. It is really frustrating though, especially with stay-at-home, that my kids can't communicate with friends on their gaming platform. The Wii U was a step in the right direction and they scrapped that.
