Nintendo Switch Minecraft problem?

I bought Minecraft a few days ago and I have a problem. My boyfriend and I wanted to play recently and I got this message: (see picture)

Well, it obviously says that I need a Microsoft account and a Nintendo Switch account… Well, I did everything and created the two accounts. Yes… This message is still there. I signed up for both. I'm also connected to my Microsoft account but the message is still there.

So my question is why is this message still there even though I have created accounts and signed up?

You need to link the accounts to Minecraft

Uhh how do I do that?

If you are on the start page, log in at the bottom left

Oh, then I've already done that

Oh hello again I was just playing a little bit and suddenly I was able to play on servers… I think it was because of my internet. But thanks anyway.
