Minecraft switch other switch worlds?

I signed in to a different console with my Nintendo Account. (Before normal switch and now switch lite.) The problem is that the worlds of one console are not on the other. (Microsoft is registered.) What can you do there?

These instructions from Nintendo should help you: https://www.nintendo.de/...49113.html

Thank you. That should solve my problem with the console around, but unfortunately it isn't. Is there another possibility?

I just did a little bit of research and found a few other ways it could work, but you always need both consoles and often both are connected to the same network, so I see black for you.
