I have this same issue. Tried everything I could think of. Can play Warframe on the switch just fine with my Nintendo account. Can login to Nintendo.com with said account and get the same error when trying to link. I was able to link my Xbox account to the new pc account I had to create. Also I had to enable MFA on the pc account and Microsoft account. Without it I wasn’t able to trade. And now I can’t trade with people that are not cross save enabled which prevents me from trading with my clan mates I’ve played with on Xbox for years…. Not happy about that and has made a few people pretty upset.

Good to know, very strange though. I was able to link my xbox account as it's the only platform I really play on. I was waiting for the cross save so I could play on my switch if I wanted as I'm LR3 and have every item.

No matter what I try, I cannot login to warframe.com as my switch account. When I try to link my account it says please create an account. I'm literally playing warframe on my switch right now, I have no idea why it won't link. Ok now it tells me, I must login to warframe on my switch. I'm playing it right now, so it's not working as intended.
